About this book
A debut novel full of magic, adventure, and romance, The Book of Doors opens up a thrilling world of contemporary fantasy for readers of The Midnight Library, The Invisible Life of Addie Larue, The Night Circus, and any modern story that mixes the wonder of the unknown with just a tinge of darkness. Cassie Andrews works in a New York City bookshop, shelving books, making coffee for customers, and living an unassuming, ordinary life. Until the day one of her favorite customers—a lonely yet charming old man—dies right in front of her. Cassie is devastated. She always loved his stories, and now she has nothing to remember him by. Nothing but the last book he was reading. But this is no ordinary book… It is the Book of Doors. Inscribed with enigmatic words and mysterious drawings, it promises Cassie that any door is every door. You just need to know how to open them. Then she’s approached by a gaunt stranger in a rumpled black suit with a Scottish brogue who calls himself Drummond Fox. He’s a librarian who keeps watch over a unique set of rare volumes. The tome now in Cassie’s possession is not the only book with great power, but it is the one most coveted by those who collect them. Now Cassie is being hunted by those few who know of the Special Books. With only her roommate Izzy to confide in, she has to decide if she will help the mysterious and haunted Drummond protect the Book of Doors—and the other books in his secret library’s care—from those who will do evil. Because only Drummond knows where the unique library is and only Cassie’s book can get them there. But there are those willing to kill to obtain those secrets. And a dark force—in the form of a shadowy, sadistic woman—is at the very top of that list.

"🌅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. ["

F. MoyerFirst 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. ["
