All it takes is one lie for the best-laid plans to go awry.

After decades of pushing away traumatic memories from childhood, Colette De Luca is ready to start a family of her own. It'll be healthy, a wish come true, with a man she believes is the love of her life. Thankfully, she thought ahead when she was younger and froze her eggs for this very moment.

Greta O'Brien, a wealthy hedge-fund manager, is forced to confront the making of her own family when tragedy strikes her twin teenage sons. As she debates whether to confess a betrayal to her husband, the ripple effects of the family's devastating circumstances begin to spread far beyond their home.

These two women, hopeful, disillusioned, and desperate, are on an emotional decades-long journey to motherhood by any means necessary. Strangers whose lives explode in the wake of a shocking event--and converge in more ways than one--Colette and Greta are forced to face the twists of fate and the choices they've made.
