But do they? On a dream honeymoon to the tropical island of Bora Bora, Mark takes Erin scuba diving. Everything is perfect. Until they find something in the water. Something that will change their lives forever. Erin and Mark decide to keep their discovery a secret. No one else need know; they trust each other implicitly. But someone else does know.
