Vivian sets forth on an archaeology expedition only to be stranded on an undiscovered island. The island's magical dome stops the ocean from swallowing the island whole, but it also keeps those on it captive. While Vivian and her small crew look for a way off the island, she meets a captivating merman and a stunning elf. There is only one problem: one of them wants to eat her heart and the other wants to protect her, but she doesn't know who. Vivian only has a few weeks to get out of the dome before she becomes prey to the heart-eater. If she succeeds everyone on the island will be set free. If she fails she and her small crew will perish.
