At 3 a.m., twenty-three-year-old single mother Macy is jolted awake by earth-shattering wails—her five-month-old son Hank is expanding at ten meters per second, bursting their entire apartment block apart. The military deploys everything in its arsenal to no avail. Then Macy discovers the impossible: only her singing can calm him down.
But Hank is just the beginning. Every few days across the globe, another newborn suddenly gigantifies—each with a distinct personality, each with a different way of losing control. The military promptly dumps them all on Macy. Within two weeks, she transforms from a cashier who couldn't make rent to the "headmistress" of five skyscraper-sized infants.
Meanwhile, deep-sea leviathans are stirring and surging toward the coast. And Macy realizes the unthinkable: her five impossibly troublesome giant babies are Earth's only line of defense.
