An ordinary man with an extraordinary mission.

While being wooed for his findings of the renowned treasure of Scavenger, Gage Finley receives a cryptic text message from his daughter. She’s been taken while on vacation—held against her will on a vessel off the coast of the British Virgin Islands.

Revered for her own talent in the water, Niki Finley is forced to make a daring dive inside a cave system chasing a rumor of a new treasure. An impossible feat—only to be attempted by seasoned professionals—will turn disastrous if she comes up empty-handed.

Can Gage find her in time? Or will this familiar stranger end the life of his only child?
