Even worse, the ghost won't leave him alone - he wants Alex and Sarah's help. Can they solve the ghost's mystery and get rid of Alex's awful rash before it ruins everything?

Just when Alex is getting close to the kickball home-run record at school, he starts getting hit with awful sneezing fits, completely messing up his game. He's allergic to a vampire! And the vampire won't leave. Can Alex and his cousin Sarah stop his horrible sneezes before they wreck recess -permanently?
