The listing, Night Circus by Erin Morgenstern (Paperback) has ended.
This book came out in September 2011, and I have reread it every year since its release, and I just finished my sixth reading. It gets more magical with each read. Between the fantastic world Ms Morgenstern has created, as well as the lyric, beautiful writing, and the (literally) enchanting characters, there is nothing about this book I dislike. I have recommended it to dozens of people over the years
