Thirteen-year-old New Yorker Rory Hennessy can see things no one else can. When a magician's trick opens his eyes to Mannahatta, Rory finds an amazing spirit city coexisting alongside modern-day Manhattan. A place where Indian sachems, warrior cockroaches, and papier-mache children live, ruled by the immortal Gods of Manhattan—including Babe Ruth, Alexander Hamilton, and Peter Stuyvesant. But Rory's power to see Mannahatta brings danger, and he is pursued by enemies, chasing history and trying to free those who have been enslaved. And when he is given the chance to right Mannahatta's greatest wrong, seeing Mannahatta may not be a gift after all. . . .
