Family is supposed to be forever. Unless you're in a family of treasure hunters.

Eighteen-year-old Ruby has grown up in her twin brothers' shadow. The whole treasure diving community applauds her brothers and abuelo for finding a famous sunken Spanish galleon. Ruby and her best friend and diving buddy Tanner spent hours searching for another galleon with a massive treasure, Dos Hermanos.

Until Tanner died.

Ruby hasn't searched for Dos Hermanos since Tanner's tragic death, but when the family's nemesis Marco tries to convince Ruby to tell him what she knows about where Dos Hermanos might lie, the race is on. Ruby's competition has too much gall and not enough conscience, but she is ready to fight for the treasure.

When Marco abducts her brothers and abuelo, Ruby is determined to search on her own and beat Marco at his own game.

But the real question is, will Ruby find the sunken treasure or lose her soul?
