New York bookseller Cassie Andrews is not sure what she’s doing with her life. She lives quietly, sharing an apartment with her best friend, Izzy. Then a favourite customer gives her an old book. Full of strange writing and mysterious drawings, at the very front there is a handwritten message:

This is the Book of Doors. Hold it in your hand, and any door is every door.

Cassie is about to discover that the Book of Doors is a special book – a magic book. A book that bestows extraordinary abilities on whoever possesses it. And she is about to learn that there are other magic books out there that can also do wondrous – or dreadful and terrifying – things.

Suddenly Cassie and Izzy are confronted by violence and danger, and the only person who can help them is Drummond Fox who has a secret library of magical books hidden in the shadows for safekeeping, a man fleeing his own demons. Because there is a nameless evil out there that is hunting them all . . .

Because this book is worth killing for.

Addictive, brilliantly written and utterly irresistible, The Book of Doors is the spell-binding, mind-bending, heart-pounding new adventure that is perfect for fans of The Binding, The Midnight Library and A Discovery of Witches . . .

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.

If you could open a door to anywhere, where would you go? In New York City, bookseller Cassie Andrews is living an unassuming life when she is given a gift by a favourite customer.

What Cassie is about to discover is that the Book of Doors is a special book that bestows an extraordinary powers on whoever possesses it, and soon she and her best friend Izzy are exploring all that the Book of Doors can do, swept away from their quiet lives by the possibilities of travelling to anywhere they want. But the Book of Doors is not the only magical book in the world. There are other books that can do wondrous and dreadful things when wielded by dangerous and ruthless individuals - individuals who crave what Cassie now possesses. Suddenly Cassie and Izzy are confronted by violence and danger, and the only person who can help them is, it seems, Drummond Fox. He is a man fleeing his own demons - a man with his own secret library of magical books that he has hidden away in the shadows for safekeeping.
