"A mysterious worldwide epidemic reduces the birthrate of female infants from 50 percent to less than 1 percent. Zoey and some of the surviving young women are housed in a scientific research compound dedicated to determining the cause. For two decades, she's been isolated from her family,treated as a test subject, and locked away ... Captivity is the only life Zoey has ever known, and escaping her heavily armed captors is no easy task, but she's determined to leave before she is subjected to the next round of tests...a program that no other woman has ever returned from."--Provided by publisher.
