Survival instinct

Stranded and left to die...Returning to Devil's Island--the place that haunts her past--is frightening enough for Abby Caldwell. When her ride home mysteriously disappears, terror starts closing in.

But then Scott's mother goes missing. Scott and Abby are forced to face the truth--all they have is each other...and ruthless enemies determined to make sure they don't leave the island alive.
