Anyone who reads knows you can be transported anywhere through a book, but what if a book could actually open a door and put you somewhere else or someplace else in time. Cassie, the main character, has been given a book, not any book, but the Book of Doors. This book is so special that numerous people will do anything to have it. Enter the friends and enemies.
I think Gareth Brown has come up with a unique twist on time travel and other bits of magic with this novel. I will admit I felt it moved a bit slow in the beginning, while setting up the story and introducing numerous characters. Also, Cassie learning to use the book was a chapter of flowery words and place dropping. After all of that was out of the way, it did pick up the pace and give more than one or two twists that in the end made for a highly satisfying read.

Thanks to Net Galley and
William Morrow for the eArc in exchange for my honest review.
