This list is a little hard to define. I started tracking it when I was compiling a list of Percy Jackson read-alikes. There is something about books featuring groups of kids (formally organized or otherwise) working together towards a common goal where each one has skills necessary for that goal to be achieved. It can make for great reading. So here are six books published in the last six months featuring teams.
6 new team-based novels
1. The Zodiac Legacy by Stan Lee, Stuart Moore, and Andie Tong
2. Has anyone seen Jessica Jenkins by Liz Kessler
3. Sisters of Blood and Spirit by Kady Cross
4. A School for Unusual Girls by Kathleen Baldwin
5. Young Houdini: The Demon Curse by Simon Nicholson
6. Powerless by Tera Lynn Childs
Clarification note: I am in no way saying that all six of these books would be suitable read alikes for Percy Jackson. They simply share a thematic element.
