*                 *              *

On a cruise with her grandmother, Erin McLean engages with three men on board. Should she throw in with wealthy Edward, intriguing “Cardigan Man” or gambler Dwayne?

Is one of these three the assassin who’s receiving orders by burner phone?

As they head south, Erin is trailed by an odd child. She argues with her grandmother, Jackie—who is also striking new friendships—over her large inheritance, which she’s determined to gift to a worthless loser.

Then, while exploring Cabo San Lucas, they witness a drug-fueled murder. Petrified they return to the ship, sworn to secrecy.

Romance might be in the making, but all is not as it seems. Deception is unveiled in attempted rape, leading Erin to a network of destruction and death. In beautiful Puerto Vallarta, she risks everything, putting herself and Jackie in harm’s way to save two innocent lives.

And the assassin receives a new order: Kill the girl.
