The current's fatal pull is powerful, but so is one detective's will to live.

When someone from Cassidy Livingston's past shows up on Lantern Beach and warns her of impending peril, opposing currents collide, threatening to drag her under. Running would be easy. But leaving would break her heart.

Cassidy must decipher between the truth and lies, between reality and deception. Even more importantly, she must decide whom to trust and whom to fear. Her life depends on it. As danger rises and answers surface, everything Cassidy thought she knew is tested.

In order to survive, Cassidy must take drastic measures and end the battle against the ruthless gang DH-7 once and for all. But if her final mission fails, the consequences will be as deadly as the raging undertow.
