Stella Sullivan loves to help the animals that turn up at her aunt Anya's veterinary clinic near her home in Montana. It is almost Halloween, and now some very strange creatures are showing up at the clinic. There's a giant python with a burn on its back, a frightened black cat, and even a hairless rat that some malicious person has painted green. Halloween also marks the beginning of a frightening time for wild woodland animals: hunting season! Scarier still, when Stella tells her aunt about a sick fawn she's spotted in the woods, Anya won't help. Has Stella's beloved aunt stopped caring about wild creatures?
