With a fresh wave of passengers soon to board the Siren of the Seas, Assistant Cruise Director Millie Sanders is shocked when she discovers she has a new roommate and fit to be tied when she learns the new roommate is none other than Danielle Kneldon, her former charge and nemesis!

Danielle’s first assignment is to ensure the ship's special 'VIP's,' a family who has won a cruise contest, have a wonderful, fun-filled vacation.

Millie discovers her coworker has other plans, which includes searching the small island of Kiriban for a missing family and collecting a hefty reward.

When Danielle, along with two of the VIP guests, vanish on the mysterious island, Millie is forced to face her fears and join the search. She enlists the help of her friends and soon they find themselves in a deadly adventure of a lifetime.

Will Millie and the gang track down Danielle and the missing passengers before the ship leaves port or will they become the next victims of the island's curse?
