Holmberg, Wall Street Journal Bestselling author "A magical, mesmerizing adventure from the very first page.

This is an extraordinary debut, rich with atmosphere. I think we've discovered something special. I dare you to step inside The Book of Doors, you won't want to leave." -- A. J. West, author of The Spirit Engineer "The Book of Doors is a beautiful, unputdownable love letter to books and the power they hold in their pages. I loved it." -- Beth Lewis, author of The Wolf Road "The Book of Doors by Gareth Brown is so good! A brilliant concept executed with mind-blowing precision, this intricately plotted book is breathtakingly clever, cinematic in scope and full of magic, wonder and heart.

" -- Anita Frank, author of The Good Liars "The Book of Doors has everything -- magic books, fascinating time loops, dreadful villains and likeable protagonists. Yet this is no children's book, this is a book aimed squarely at adults. It's clever, fast-paced and so very, very dark. I absolutely loved it." -- M. W. CRAVEN, author of the Washington Poe series.
