The Hidden Witch
This sequel to The Witch Boy by Molly Knox Ostertag picks up with Aster finally getting to follow his dream of going to school for witches. He encounters difficulty, however, when he faces some discrimination from the teachers there. Charlie, his best friend who is not a witch, is back in school and befriends a strange new girl who keeps to herself and has many secrets.
I didn't like this one as much as I liked The Witch Boy but I did enjoy it and I think it is worth the time to read, especially if you enjoyed The Witch Boy.
