No dog can be trusted--and no dog is safe in this gripping fourth book in the second Survivors series. From Erin Hunter, #1 nationally bestselling author of Warriors, Survivors is full of "wild and wonderful adventure" (Kirkus Reviews, starred review) that will thrill fans of Spirit Animals and Wings of Fire. The Wild Pack is in high spirits after rescuing Alpha and Beta's pups. Only Storm believes that danger still walks among them--and it won't be long before the traitor dog strikes again. She must convince her Packmates to stand together against the most malicious and elusive enemy they have ever known...before terror and doubt tear them apart.
