About this book

Cassie Andrews leads a quiet, unremarkable existence in a New York City bookstore until the sudden death of a beloved regular customer leaves her with an unexpected inheritance: a mysterious, unassuming volume known as the Book of Doors. This is no ordinary text; its pages hold the impossible power to turn any door into a gateway to anywhere in the world. Cassie’s discovery quickly shatters her mundane reality when she is tracked down by Drummond Fox, a guarded, enigmatic librarian who protects a collection of rare, powerful tomes.

Drummond reveals that Cassie’s book is the most coveted piece in a dangerous, hidden history, making her a primary target for ruthless collectors who will stop at nothing to seize its potential. As a sadistic, shadowy adversary closes in, Cassie and Drummond are forced into an uneasy alliance. Bound together by the necessity of survival, they must navigate a world of shifting thresholds and ancient secrets.

Caught between a newfound sense of wonder and the encroaching darkness, Cassie must decide how far she is willing to go to protect the magic she has unearthed, and whether she can trust the haunted man who holds the key to her survival.

Great Read

"🌅What if books didn’t just change your life—they could change the very fabric of reality? That’s the irresistible hook at the heart of The Book of Doors. This genre-blending debut novel combines the wonder of magical realism with the pulse-pounding intensity of a thriller, all wrapped in the quiet, bookish charm of a story about an ordinary woman thrust into the extraordinary. The novel follows Cassie Andrews, a shy, solitary bookseller in New York whose life revolves around the comfort of stories—until one snowy night when her favorite elderly customer dies suddenly, leaving behind a mysterious volume known only as the Book of Doors. The concept is deceptively simple: with this book, any door can become every door. But as Cassie experiments with its strange powers, she discovers that some books don’t just open worlds—they invite danger. Soon she’s drawn into an ancient, hidden battle over magical books that can manipulate time, grant powers, and shape reality itself. Alongside her brash best friend, Izzy, and the enigmatic Drummond Fox—a guardian of magical texts—Cassie must decide whether she dares to protect the book or risk losing everything she holds dear. This is a novel that plays with big ideas: power, memory, the meaning of freedom, and the age-old allure of stories as both an escape and a weapon. The magic system Gareth Brown created is grounded in books themselves and is not only clever but beautifully executed. Each magical book reflects something essential about its owner, an idea that will deeply resonate with readers who find pieces of themselves in the books they love. Cassie, far from a chosen-one stereotype, is hesitant, flawed, and deeply relatable, and her growth is both believable and satisfying. Izzy adds humor and sharpness, while Drummond’s quiet sadness gives the story emotional depth. The villains are genuinely chilling—one in particular left me anxious—and the stakes feel both intimate and epic. That said, readers should be prepared for a few things. The pacing, especially in the first half, can feel uneven as the world-building takes shape. Some chapters linger longer than necessary, and the writing, while richly descriptive, occasionally veers into overly elaborate territory that may slow down those looking for a tighter, action-driven read. The violence, too, is more vivid than I expected—while never gratuitous, there are moments of brutality that could be unsettling for sensitive readers. Content warnings include depictions of death, violence, and psychological manipulation. But these are minor critiques in the context of what is ultimately a mesmerizing, imaginative, and deeply thoughtful story that I enjoyed immensely! The twists are genuinely surprising, the tension builds with precision, and the payoff is both satisfying and thought-provoking. I finished the last page feeling the way I do after finishing books that stay with you for years: a little breathless, a little haunted, and entirely transported. The Book of Doors is more than just a magical adventure—it’s a love letter to the transformative power of stories themselves. For anyone who has ever dreamed of stepping through a doorway into another world, this book is an absolute must-read. I’m already anticipating Gareth Brown’s next book. ["

First half a bit slow; second half much better

"I would classify this book as Fantasy since the story is driven by the idea that a set of magical books exists, where each book imparts its own unique set of powers to whomever is holding that book. Still, Amazon’s “Product Details” calls the book “Time Travel Science Fiction” – probably because I’ve never seen a book classified as Time Travel Fantasy. Yet, isn’t the whole idea of time travel just wishful thinking rather than scientifically possible? Anyway … The protagonist (Cassie) is gifted an odd looking book (the Book of Doors). Does she know the book was magical? Not initially; but odd, wondrous things certainly made it appear that perhaps it is magical. Does Cassie’s life remain peaceful and mundane? Of course not. The story is slow getting started. And during that time, I’m thinking: this story should explain how all these magical books came to be. (To the author’s credit, he does explain that -- after a fashion, anyway.) The second half of the book was much better. More action. More heart. More urgency. More twistiness in the storyline. Bottom Line: A twisty, entertaining storyline. Suspend your skeptical nature and then just enjoy the ride. A heartwarming, fantastical read. Note: There is one point in the story where I was shocked with what the author allowed to happen within the story. It was just against the basic “flow” and “feel” of the story. As a reader, I just had to power through it. If you hit this same part with similar emotions as I had, just power through it. Ultimately, you won’t regret it. ["

Makes you wonder what "time" means

"This book is heavy. The book itself is hefty, but what I'm referring to is the material. Makes you wonder what "time" means. The author does a brilliant job plotting a complex story that weaves together a lovely cast of characters - good and evil - and has you second guessing a lot of what you read and expect to be true, but is not. Unique plot: there are elements here that are completely fresh. I can't readily compare it to another novel. And the ending is sweetly satisfying. No spoilers in this review but I will say I read this without much knowing about the book, based on the recommendation of several other reader friends, and I'm glad I had that blank slate without much expectation because I was stunned. It is tender when you aren't expecting it, gasp-inducing, and thought-provoking. I will read it again in a few years, for sure. 100% recommend this gem of a novel that I will long remember. ["

Good, light read

"The magic in the Book of Doors allows adventure across borders and time. It takes you to picturesque spots in Europe and America, where characters hide out from evil hunters of magic books. These books have a wide range of powers — from bringing joy to intense pain. The Book of Doors serves as one book to rule them all, and it falls into the hands of our main character, Cassie, a homebody thrust into peril that elicits her courage, loyalty, and practical wisdom. The plot is complex but easy to follow. It takes a few unpredicatable swerves. Magic leads Cassie and her friends into trouble and helps them get out of it, without “jumping the shark.” The writing is clean and simple. But efforts to dress up the prose are unsophisticated. It’s good, light reading. ["
