Learning From The Dead
Book Two in The Kylxon Chronicles

Pack must face the testing by the dead ones, but he has little time to wonder about whether he passes or fails as he and Sydney search to save Mrs. Wamdoffer. Along they way they run into a very weird girl, Balford Memmer and his thugs, and discover Mrs. W isn't the woman they thought she was. But then, Pack isn't the boy Memmer and Mrs. W think he is!
