“An epic that hits all the perfect notes of science, magic, and sweetness.”   Kirkus Review

“An endlessly stimulating sequel that caters to intellectually fearless readers.”   –Kirkus Review

The Bartholomew the Adventurer Trilogy and the Orville Wellington Mouse adventures are multi-leveled stories which have been compared to Chronicles of Narnia, The Hobbit, and Neverending Story. The books have underlying themes of ethics, metaphysics, philosophy, quantum physics, and personal growth. A common theme is the idea that there is no magic, only science we don’t understand. The books were written to provide an alternate way to view the world we live in. To see all life as a single force, all life equally precious, no matter the form. A world where violence is not necessary, a world where the protagonists are changed forever by their difficult choices, by their own sacrifices. A world of empathy, kindness, and love. And of course, ten foot tall ancient robotic rabbits and gigantic carnivorous centipedes living on post apocalyptic planets!

The Bartholomew the Adventurer Trilogy

A romping tale of adventure set in the far distant future after humans have vanished from the planet. The protagonist is a self centered rabbit named Bartholomew who sets out in search of a missing object which he is unable to describe or name. Along the way he meets his adventuring companion, Oliver T. Rabbit, a brilliant scientist who also undergoes a deep transformation in the trilogy, coming to understand that there is no magic, only science, whether it’s time travel, parallel dimensions, manifesting physical objects with thoughts, or reincarnation. Their adventures take them to lost cities, parallel universes and other planets, along the way meeting a host of memorable characters including ancient robotic rabbits, the Tree of Eyes, the Singing Monks of Nirriim, the Blue Spectre, and Edmund the Explorer.

All the events in the trilogy are based on known metaphysical phenomena and philosophical beliefs which have been in existence for thousands of years. That being said, The Bartholomew the Adventurer Trilogy can be read and enjoyed by a young person with no knowledge of metaphysics or philosophy. The books are written very simply, but are multileveled, having been compared by readers to Chronicles of Narnia, The Alchemist and The Hobbit.  If you’d like to learn more about the stories behind the stories, just click on “The Real Stories Behind Bartholomew the Adventurer”.

2016 Gold Medal Winner Best Young Adult Adventure Book
Readers Favorite International Book Award

The Orville Wellington Mouse series is filled with grand adventure, friendship, and humor while retaining the deeper themes of ethics, metaphysics, science, and personal growth. A fun and inspiring read for all ages, Orville Wellington Mouse titles include:

Orville Mouse and the Puzzle of the Clockwork Glowbirds

Orville Wellington Mouse lives with his Mum in the quiet fishing village of Muridaan Falls, Symoca. His life takes an unexpected turn when he learns his best friend Sophia Mouse is not only from another planet, but is also a member of the Shapers Guild, a group of powerful mice who are able to convert their thoughts into physical objects.

When Orville notices a group of seven glowbirds exhibiting rather extraordinary behavior, he and Sophia attempt to uncover the origin of the unusual birds but soon find themselves enmeshed in a fiendish plot to embroil Symoca in a horrific war. Captured by the powerful and mysterious Red Mouse, the two adventurers are hurled through a spectral door into the terrifying world of Periculum, home of the dreaded giant carnivorous centipedes.

With help from the secretive Metaphysical Adventurers, Proto the Rabbiton, the Mad Mouse of Muridaan, a gigantic Gnorli bird, some ghostly Anarkkian warriors, and the enigmatic Monks of the Blue Robe, Orville and Sophia must find their way home and stop the evil Red Mouse before he destroys Symoca.

Orville Mouse and the Puzzle of the Shattered Abacus

Orville Wellington Mouse unwittingly sets off a galaxy shaking chain of events when he buys his mum a lovely birthday necklace from Miraculum’s Fine Antiques. When Orville and his best friend Sophia Mouse observe a small glass marble breaking the laws of physics they set out to discover the cause of its extraordinary behavior, unexpectedly revealing the marble’s astonishing connection to his mum’s new necklace.

The pair of young Metaphysical Adventurers soon find themselves in a desperate race to prevent time from stopping in their galaxy. With help from their good friend Proto the Rabbiton, Master Marloh of the Metaphysical Adventurers, the Mad Mouse of Muridaan, Ollo the Rock Mouse, Myrmac the Brave, the King of Ants, the Shrieking Terror of Tatuid, and Captain Patcher of the Dragonfly Squadron, Orville and Sophia must travel to the terrifying apocalyptic planet of Varmoran to discover the incredible truth that lies within the mysterious blue marble.

Orville Mouse and the Puzzle of the Capricious Shadows

When Orville Mouse rescues an errant windblown hat on his way to work, he soon discovers the hat’s shadow is not behaving as it should be. While attempting to discover the cause of this curious phenomenon, Orville and his best friend Sophia Mouse uncover a terrifying secret, soon finding themselves in a desperate race to prevent the imminent destruction of uncountable parallel worlds.

With help from their old friend Proto the Rabbiton, mysterious Madam Molly, a wistful robotic curator named Copo, a pair of gigantic vacationing insects, a ghostly engineer, the vaporous Others, and the simmering Forest of Thorns, the two stalwart adventurers must retrace the journey of a centuries old explorer named Haukesworth Mouse to the lost world of Tectar and a terrifying confrontation with Mendacium the Dark Wizard in the dank and dismal dungeons of infamous Castle Caligari.

Orville Mouse and the Puzzle of the Last Metaphonium

When Orville Mouse wakes up from a terrifying nightmare to find a mysterious red book in his bed, he and his best friend Sophia set out to decipher the cryptic manuscript, convinced the book is connected to the disappearance of Orville’s neighbor, Aislin Mouse. Their quest takes them to the lost city of Cathne where an astonishing turn of events catapults the adventurers into a desperate interdimensional race to save Aislin.

Accompanied by their old friend Proto the Rabbiton, Orville and Sophia enter the bewildering and terrifying world of Elysian in search of Aislin Mouse. With help from a beautiful ghost mouse, Orville’s cantankerous neighbor Ebenezer, Puella the Wise One, crusty old Captain Tobias, an austere monk named Brother Solus, dreamy Madam Beasley, and Charon the Ferrymouse, the stalwart adventurers must uncover the secret of the last Metaphonium and confront the horrific burning charcoal stick creature known only as the Shadow King.

Orville Mouse and the Puzzle of the Sagacious Sapling 

Orville’s terrifying dream of being cooked in a stewpot by ferocious purple birds marks the beginning of an extraordinary quest to prevent Muridaan Falls from disappearing into the past. In the midst of the worst winter storm in memory, Orville and Sophia must discover the connection between two ancient Mintarian rings, a gold pocket watch that runs backwards, and an extraordinary tree that Orville claims to have seen.

Orville, Sophia, and Proto journey to the unsettling Plane of Turris where a startling truth is revealed, redirecting the intrepid Metaphysical Adventurers to the sweltering prehistoric jungle world of Ferus.  With help from Science Guild Master Lybis, mysterious Madam Molly, the enigmatic Watcher, ferocious Captain Beaky, amazing Amanda Mouse, the angry ghost of Captain Ryle, and Squeaky the RoboPup, they must stop the Great Thaumatarian Time Wave before Muridaan Falls becomes history.

Why did I write the Orville Mouse series?

Why did I write the Orville Mouse series?

Two reasons. Both of them are my grandchildren.

In today’s world it’s hard to find good role models for kids. So much anger, prejudice, divisive thinking, and the all too prevalent desire for instant gratification. A tough world to raise kids in. So along came Orville Mouse and his best friend in the world, Sophia Mouse.

Orville is a very intuitive, empathetic mouse possessing a stunning imagination and a deep curiosity. He’s also scared of a great many things, unlike Sophia, a daredevil brilliant mouse who “dropped like a bossy know-it-all gift from above into Orville’s life”. The two best friends embark on their amazing interdimensional adventures, along the way overcoming seemingly impossible obstacles without ever resorting to violence. They help each other overcome personal fears and loss, while coming to understand that a creature’s true inner self is far more important than it’s outer physical form. I could go on and on, but I won’t. I’ll just say my grandkids love these books, as do their friends. The stories are written simply, but with many layers. I have readers who are 9 and readers who are 90.

This is taken from a review on Amazon:

“If you are a quiet, gentle, kind soul, these books are for you — old or young. If you like a wildly imaginative, strapping-good adventure full of small acts of great love, these books are for you. If you enjoy science, philosophy, and dignity-for-all these books are also for you.

My daughter and I often refer to these characters and concepts which have ignited our imaginations throughout the course of our days. I love that we have common content to discuss and ponder together. Most of all, we can’t shake the way reading these books makes us feel: Joyful and Hopeful!”

Hi everyone! The Orville Mouse and the Puzzle of the Clockwork Glowbirds audiobook is finished and is now available on Audible, iTunes, and Amazon!


My hat is off to Jason Zenobia, the incredibly talented voice actor who brought all these wonderful characters to life. It was a joy working with him, discussing the personality of each character, working on the different voices. He is truly the consumate professional, so easy to work with, creative, a perfectionist, and best of all he has a work ethic equal to mine. Thank you, Jason! You did an amazing job!

And in case you were wondering — Proto is hilarious and Draken Mouse is sooooooo evil!! And don’t even get me started on the Thirteenth Monk! So much fun!!




Reviews in for Sagacious Sapling!

Here are some highlights from the first four editorial reviews on Orville Mouse and the Puzzle of the Sagacious Sapling. All four reviews were 5 stars!

Another wonderful book from this author. I am thrilled at how well Tom Hoffman incorporates science and language skills into the story, as well as encouraging children to be accepting and kind to others. Fabulous descriptions, incredible adventure sequences, strong support for the values of a good education, and being a friend to others are only part of what makes Orville Mouse and the Puzzle of the Sagacious Sapling such a wonderful book. Tom Hoffman does a magnificent job in portraying the depth and breadth of science at work in the world around us, and constantly yet subtly encourages the acceptance of others that may be different. As Book 5 in the series, it would be a good idea to read the others first so that you have a complete understanding of the references that are made throughout this volume, but reading all of the Orville Wellington Mouse Adventure stories is certainly a great idea for plenty of reading fun.

Orville and Sophia’s friendship is a joy to revel in, and their growing closeness never seems to preclude their shared penchant for joking, teasing and making sure neither one of them gets too full of themselves. Hoffman’s fondness for his Metaphysical Adventurers shines out on every page, and his delight in their companionship is quite infectious. As I began reading, I soon felt as though I had come home again and was hoping, along with Proto, that an adventure was indeed afoot. Hoffman transcends genres with his Orville and Bartholomew Rabbit series. While undeniably cracking good epic fantasy, there’s a vibrant strain of steam punk, metaphysics, high-tech science fiction and good old-fashioned adventure running through each of his books, and this one is no exception. I loved the time traveling aspect of the story as well as Proto’s well-measured insights into sentience and awareness of self.

Proto comes into his own most wonderfully in this book. Watching as he becomes friend and mentor to Leaf is an awe-inspiring thing. I’m most definitely looking forward to Hoffman’s next book. While this is the last in his Orville Mouse series, I don’t doubt for one moment that Orville, Sophia, Proto and Leaf are out there looking for puzzles, finding fearsome monsters for Proto to delight over and indulging in snapberry pie and tasty little cakes. Those adventures don’t end, even if the series has drawn to a close. Orville Mouse and the Puzzle of the Sagacious Sapling is exciting, fast-paced and a lot of fun to read. It’s most highly recommended.

No need to reveal the plot line of Orville Mouse and the Puzzle of the Sagacious Sapling. Tom Hoffman’s uniquely appealing creation, mighty but fearful Orville, declares it precisely: “Let’s go save the universe.” What does need mentioning is the incredibly satisfying and stimulating camaraderie of Hoffman’s characters as they band together to fulfill – against some mighty intimidating and powerful odds – such an infinitely important mission. What holds readers glued to Hoffman’s books and keeps them coming back for more is the deeply human warmth and friendship shared between such small but courageous creatures. In the end, it is these friendships based on love and humor that assure our grand crusaders’ ultimate success. And, along the way, generous allotments of subtle wisdom and tasty snapberry pies for me. Er … for us, the appreciative readers.

Orville Mouse and the Puzzle of the Sagacious Sapling is my first foray into the work of Tom Hoffman and indeed his fantasy world of Orville Mouse. This book is the fifth adventure involving these characters and although it is not necessary to have read the previous books, it is always an advantage, I feel, to read a series in order. As a reader, once you get your head around the idea that this story is a fantasy adventure and indeed the two main characters are actually mice, the characters, their foibles and traits very definitely do grow on you. Orville and Sophia are truly sweet and adorable characters, but much of the humour and enjoyment I derived from the story came from the two offbeat characters; Proto (a robot of sorts) and of course, Leaf, the Sagacious Sapling. I loved the way they analysed Orville’s jokes and tried to replicate the humour themselves. The idea of logical thinking, programmed machines beginning to adapt and understand humour, while not novel, was definitely intriguing.

Hoffman has probably targeted the Orville Wellington Mouse sagas at the Young Adult market, but to be perfectly honest, I would suggest there is nothing in this book that would preclude it from being read at a younger age and also by older readers. It is a good, old-fashioned, swashbuckling adventure tale, whose two protagonists just happen to be a couple of mice. It is an excellent read and I would definitely recommend it.
