Anne Heltzel’s debut novel, Circle 9
Full disclosure: I read an advance copy, so I’m unable to quote from the book.

A fairly short novel, but not without depth, Circle 9 is the story of Abby, a girl who wakes with no memory, covered with ashes, with only a sense of connection to the boy by her side. This is a powerfully engaging story with dark themes, and no easy answers. I couldn’t put it down and read it in one sitting. I highly recommend, but be warned that it is not a happy story.
