From the publisher:

Erin is a documentary filmmaker on the brink of a professional breakthrough, Mark a handsome investment banker with big plans. Passionately in love, they embark on a dream honeymoon to the tropical island of Bora Bora, where they enjoy the sun, the sand, and each other. Then, while scuba diving in the crystal blue sea, they find something in the water....

Suddenly the newlyweds must make a dangerous choice: to speak out or to protect their secret. After all, if no one else knows, who would be hurt? Their decision will trigger a devastating chain of events....
