Resumen:

Give a Dog a Bone (Creatures, Bk. 6 ) : Pippa's having real problems with her roommates, Jayne and Liddy, on the school trip. Those two really hate each other. So when Jayne finds a bone under her bed, it's pretty obvious who put it there. Just a sick joke, right? But then the other things start. Snuffling noises in the night. A weird shadow, following Jayne about . . . Things Liddy couldn't possibly be doing. Not unless something is helping her . . .
