A year ago at the elite Marshall Summer Naval School, Margaret Moore presumably drowned herself from heartbreak, but this summer, the remaining girls from Deck Five will ensure Margaret's story is heard.
Each summer the girls of Deck Five come back to Marshall Naval School. They sail on jewel-blue waters; they march on green drill-fields; they earn sunburns and honors. They push until they break apart and heal again, stronger. Each summer Margaret and Rose and Flor and Nisreen come back to the place where they are girls, safe away from the world: sisters bound by something more than blood. But this summer everything has changed. Girls are missing and a boy is dead. It's because of Margaret Moore, the boys say. It's because of what happened that night in the storm. Margaret's friends vanish one by one, swallowed up into the lies she has told about what happened between her and a boy with the world at his feet. Can she unravel the secrets of this summer and last, or will she be pulled under by the place she once called home?
