"Promises mean nothing on this ship. Tell me the password." Nobody knows what really happened when Rachael Baptiste's mom disappeared a week ago. So when Rachael's second-grade classmate Raul tries to break into her mom's computer only to be chased away by giant talking dogs, she follows him into the night and discovers that Raul-and her mom-have caught a magical sickness that lets them turn into magical animals, or Exotics. A group of evil Exotics, the Shadow Dogs, kidnap Rachael and Raul to a mysterious ship and try to force them to tell them her mother's secrets...but Rachael's not talking. Instead, she's trying to find a way to escape the ship and rescue the Exotic kids trapped on board, waiting to be sold as pets...or are they?
