I tried and tried to figure out how best to describe this book. It's not exactly complicated per se, but it's very difficult to explain or describe to someone without giving away certain things. So, even though it may be cheating, I've decided that the best way to summarize this book is to use the description from the back, which reads as follows:
This book was truly extraordinary. It could be one of the best books I've ever read. Everything from the intertwining story lines to the way it's written is just beautiful. It's intriguing, perceptive, and strangely romantic, but in a way that makes every aspect of this book fall perfectly into place - much like the pieces of the circus. I can't even imagine how such a concept came to be, but Erin Morgenstern is simply brilliant."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 RĂªves, 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 performers to the patrons, hang in the balance, suspended as precariously as the daring acrobats overhead."
Go read this book. You won't regret it, I assure you.
