The Boy Who Returned from the Sea by Clay Morgan

When The Boy Who Spoke Dog was published, Publishers Weekly wrote: "The pacing is swift, and the surprising and touching finale begs for a sequel." In this continuation of the first book, Clay Morgan has reunited Jack and his beloved dog, Moxie, on the island where they first met. Jack is not the only human on the island: The mysterious and dangerous Blackburn Jukes is there, too, searching for the valuable amber hidden in the bogs of the island. Moxie and Jack soon realize that they must work together in order to protect themselves and their island from this intruder in this action-filled novel.
