Skelee is missing, and his friends, both from the human and Spooky Worlds, are on a quest to find him. No thanks to Theo, heir to the Spooky World empire, Skelee has been banished to an undisclosed location that is called a "place of no return" for all Spooky World creatures. Will Skelee be found? Who will rescue him and bring him back to the two worlds that he adores? In Skelee Boy and the Isle of the Dead, the human kids: Nate, Taylor, Iggie, and Cynthia embark on a perilous mission to find Skelee. Yet, no one anticipates that Theo has a deadly, malicious plan that may destroy the worlds that Skelee has worked so hard to unite.
