Renowned children?s-book author Sara Young makes an ambitious foray into adult fiction with My Enemy’s Cradle, a tale of one woman?s survival during WWII.

When the family grows increasingly concerned about Cyrla?s safety (and theirs), they hide her in one of the last places the Nazis might look: Lebensborn, a birthing center for Aryan babies.
