A true friendship survives the test of time. But what about surviving a nine-tailed fox?

Last summer, Ronnie Miller's world turned upside down. She'd never believed in ghosts, or witches, or magic--until her time at Camp Foster, where she learned she was a witch. Magic was real. And some of it wanted to kill her.

Now back at Camp Foster for winter break, Ronnie and her friends Jack, Olivia, and Sam can't wait to enjoy all that winter camp has to offer. They're excited to be back together, enjoying camp without worrying about mysterious forces that want to kill them. But when campers begin inexplicably falling ill, Ronnie and friends suspect the supernatural is at play.

A gumiho--a nine-tailed fox spirit who feeds on people's life energy--is stalking the grounds at Camp Foster. And she's hungry.

The perfect book for fans of Claribel A. Ortega and Graci Kim. Join Ronnie and her friends as they unravel the mystery of the gumiho and discover the true meaning of friendship.
