The Fourth Level - Book Thirteen - Masquerade (Paperback) (ISBN-13: 9781988765365)

In celebration of Diana Cambridge and Tristan Merrick's graduation from high school, Allodia de la Cabernet decides to take the couple, and her brother, Charlemagne de la Cabernet, to the utopian island of Isla Paraiso in the Caribbean to meet with the Cabernet parents, Everest and Vienna de la Cabernet, who are on a humanitarian mission to assist some displaced islanders.

However, seeking to assist the islanders in his own manner, Charlemagne de la Cabernet focuses on assisting an islander child that has come down with a mysterious illness. Charlemagne's efforts soon find himself face-to-face with a mysterious Witch Doctor he believes to be responsible for the kidnapping of children on the island, or so it initially seems. Both Diana and Tristan assist Charlemagne in his endeavor to unmask the evil that lurks within this island paradise.

Will Charlemagne and the couple be able to unmask the evil on the island? The Witch Doctor? Is this island truly a paradise, or a façade of one? Are the evildoers the only ones that are wearing masks...?
