The Night Circus by Erin MorgensternRead about the other entries on the list.
“The circus arrives without warning,” begins The Night Circus. “No announcements precede it. It is simply there, when yesterday it was not.” I love the opening of this book, in part because it captures for me an essential quality of intrusive, fairy tale magic: one day everything is as it was, and the next day something unexpected has happened to change it forever. There are several magicians in this book and Morgenstern moves between their stories and those of complete outsiders to the circus. This separation lets us experience the story’s magic, both beautiful and cruel, from the inside and at the same time to long for it when we stand outside the circus gates. It’s apt that the circus aficionados call themselves “rêveurs” or dreamers, as dreaming itself is an intrusive magic.
