Never Trust a Dead Man (Vivian Vande Velde)

I picked up this YA mystery on impulse, based on reviews in Amazon. In a medieval village, a teen is condemned to death for a murder he didn't commit. He runs into a witch who agrees to help him find the real murderer by bringing back the spirit of the dead man in the body of a bat, but he doesn't know who killed him. More bikinis ensue before all is resolved. It was pleasant snough, but nothing special.
