Daughters of January — E.Z. Rinsky

Humanity has succumbed to a man-made plague. Only eleven people survive, by fleeing out to the middle of the Atlantic on a cargo ship. They're an unlikely group of survivors: among them a middling French photographer, a frail hedge fund manager, and a manic purveyor of artisanal salad dressing. As the sailors struggle to adapt to their surreal new lives, they resort to preposterous power grabs, desperate trysts, and paranoid scheming. Ultimately their only chance to reboot humanity rests with the cult responsible for the end of the world: The Daughters of January.
