A mother’s worst nightmare, a chance at redemption, and a deadly secret that haunts a family across the generations.

There’s only room for one mother in this family.

Claire Abrams’s dreams became a nightmare when she passed on a genetic mutation that killed her little boy. Now she wants a second chance to be a mother, and finds it in Robert Nash, a maverick fertility doctor who works under the radar with Jillian Hendricks, a cunning young scientist bent on making her mark—and seducing her boss.

Claire, Robert, and Jillian work together to create the world’s first baby with three genetic parents—an unprecedented feat that could eliminate inherited disease. But when word of their illegal experiment leaks to the wrong person, Robert escapes into hiding with the now-pregnant Claire, leaving Jillian to serve out a prison sentence that destroys her future.
