In this hilarious novel from Pulitzer Prize finalist Lydia Millet, a honeymooning couple makes friends with a marine biologist who discovers genuine mermaids in a coral reef-and who, the next night, apparently drowns in her hotel bathtub. As a resort chain swoops in to corner the market on mermaids, the newlyweds (opinionated, skeptical narrator Deb and handsome online gamer Chip, the world's friendliest man) join forces with other vacationers-including an ex-Navy SEAL with a love of explosives and a hipster Tokyo VJ-to protect the mermaids from the corporate 'Venture of Marvels' that wants to turn their habitat into a theme park.
