The Night Circus by Erin Morgenstern
How to describe this book? Richly imagined, haunting, hypnotic, beautiful, totally original. I've really never read anything else like it. Here's the summary from Goodreads:
The circus arrives without warning. No announcements precede it. It is simply there, when yesterday it was not. Within the black-and-white striped canvas tents is an utterly unique experience full of breathtaking amazements. It is called "Le Cirque des Reves," and it is only open at night.
But behind the scenes, a fierce competition is underway--a duel between two young magicians, Celia and Marco, who have been trained since childhood expressly for this purpose by their mercurial instructors. Unbeknownst to them, this is a game in which only one can be left standing, and the circus is but the stage for a remarkable battle of imagination and will. Despite themselves, however, Celia and Marco tumble headfirst into love - a deep, magical love that makes the lights flicker and the room grow warm whenever they so much as brush hands.
True love or not, the game must play out, and the fates of everyone involved, from the cast of extraordinary circus per-formers to the patrons, hang in the balance, suspended as precariously as the daring acrobats overhead.
