Rhine and Gabriel have escaped the mansion, but they're still in danger. Outside, they find a world even more disquieting than the one they ran away from. Determined to get to Manhattan and find Rhine's twin brother, Rowan, the two press forward, amid threats of being captured again...or worse.

The road they are on is long and perilous--and in a world where young women only live to age twenty and men die at age twenty-five, time is precious. In this sequel to Lauren DeStefano's harrowing Wither, Rhine must decide if freedom is worth the price--now that she has more to lose than ever.
