We Shall Sing a Song into the Deep

Remy is a Chorister, rescued from the surface world and raised to sing in a choir of young boys. Remy is part of a strange crew who control the Leviathan, an aging nuclear submarine, that bears a sacred mission: to trigger the Second Coming when the time is right. But Remy has a secret too - she's the submarine's only girl. Gifted with the missile's launch key by the Leviathan's dying caplain, she swears to keep it safe. Safety, however, is not the priority of the new caplain, who has his own ideas about the mission. When a surface-dweller is captured during a raid, Remy's faith becomes completely overturned. Now, her last judgement may transform the fate of everything.
