Cyrla's neighbours have begun to whisper. Her cousin, Annika, is pregnant and has passed the rigorous exams for admission to the Lebensborn, a maternity home for Aryan girls carrying German babies. But Annika's soldier has disappeared, and the Nazis confiscate fatherless children. Cyrla, sent from Poland to hide with her Dutch relatives, has been warned that her neighbours know she is half Jewish. She won't be safe with them for long. A cruel twist of fate places Cyrla with the terrible choice between certain discovery in her cousin's home and taking Annika's place in the Lebensborn - Cyrla and Annika are nearly identical. If she takes refuge in the enemy's lair, can Cyrla fool the doctors, nurses, guards, and other mothers-to-be? How will she escape before they discover she is not who she claims?
