A mysterious worldwide epidemic reduces the birthrate of female infants from 50 percent to less than 1 percent. Medical science and governments around the world scramble in an effort to solve the problem, but twenty-five years later there is no cure, and an entire generation grows up with a population of fewer than a thousand women.
Zoey and some of the surviving young women are housed in a scientific research compound dedicated to determining the cause.
For two decades, sheās been isolated from her family, treated as a test subject, and locked awayātold only that the virus has wiped out the rest of the worldās population.
Captivity is the only life Zoey has ever known, and escaping her heavily armed captors is no easy task, but sheās determined to leave before she is subjected to the next round of testsā¦a program that no other woman has ever returned from.
Even if sheās successful, Zoey has no idea what sheāll encounter in the strange new world beyond the facilityās walls. Winning her freedom will take brutality she never imagined she possessed, as well as all her strength and cunningābut Zoey is ready for war.
