The Book of Doors: A Contemporary Fantasy Race Against Time to Protect a Magical Library from Sinister Forces

INTERNATIONAL BESTSELLER

A debut novel full of magic, adventure, and romance, The Book of Doors opens up a thrilling world of urban fantasy for readers of The Midnight Library, The Invisible Life of Addie Larue, The Night Circus, and any modern portal fantasy 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 magical 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.

Not sure how I feel about this book. Some really dark parts but hopeful in others.

This was a compelling concept- in the nothingness Cassie created the magic books that cause wonder and chaos. The book seller, the librarian, the hunter, and the woman are all converging on Cassie and her bestie Izzy.

Thoroughly enjoyed this one. The premise was at once familiar and unique, and it was not at all the story I thought it would be. My one gripe is that there’s a major plot hole to the story that I don’t feel was resolved or explained well enough at all. Otherwise, it was a great book.

I was surprised by how much I enjoyed this - :) At first I was hesitant - although a big fan of fantasy in my youth I was not sure how much I would enjoy this genre in my adult years - HOWEVER I was pleasantly surprised and absolutely smitten by this story and it's characters - what a treat! What I enjoyed the most was the nostalgic tone and sentimentality woven throughout - there were many moments where I found myself drawn into a contemplative state vis-a-vis my own life and choices (and only good books have this effect on me!) This is a warm, heartfelt and deep read that encourages reflection and introspection - a must-read - :)
