Charlie Bone and the Castle of Mirrors is Bk4 in the seven-book series. I picked up my copy of Zita the Spacegirl at the thrift store … and immediately ordered the rest of the series online. Funny, exciting, and a solid favorite. And I’m always there for stories with Shakespeare allusions. The Total Tragedy of a Girl Named Hamlet is about a girl whose parents live a few centuries behind the rest of the world and whose little sister is a genius who’s joining her in the eighth grade.
