"If you have ever craved a story that will leave your heart racing, your lungs gasping from the numerous twists and turns, and your soul heaving from carrying an ensemble cast, you will find all that in these pages."--New York Times best-selling author Roshani Chokshi
Ana Dakkar is a freshman at Harding-Pencroft Academy, a five-year high school that graduates the best marine scientists, naval warriors, navigators, and underwater explorers in the world. Ana's year culminates with the class's weekend trial at sea, the details of which have been kept secret. She only hopes she has what it'll take to succeed. All her worries are blown out of the water when, on the bus ride to the ship, Ana and her schoolmates witness a terrible tragedy that will change the trajectory of their lives.

The professor accompanying them informs Ana that their rival school, Land Institute, and Harding-Pencroft have been fighting a cold war for a hundred and fifty years. Now that cold war has been turned up to a full broil, and the freshman are in danger of becoming fish food. In a race against deadly enemies, Ana will make amazing friends and astounding discoveries about her heritage as she puts her leadership skills to the test for the first time.
