There are big changes at DSA. A new student has arrived... and she's a girl. Janice is big and strong and better than all the boys at sword fighting and jousting. Erica's happy---she can finally stop masquerading as a boy. Mordred the headmaster is happy--- he has a big bag of gold from janice's rich parents, And Wiglaf is happy---his mischievous pet dragon is off visiting family and can't cause trouble for a while. Sounds like everything at dear old DSA isjust find and dandy, right? Wrong! Because a vengeful ghost is on the loose, determined to get back his stolen treasure or destroy the school.
