In this riveting prequel to her novel Little Mercies, New York Times bestselling author Heather Gudenkauf explores how even the smallest lies can have far-reaching consequences.

When the body of a woman is discovered in a local park—with her bewildered four-year-old son sitting beside her—veteran social worker Ellen Moore is called in to assist in the police investigation. Positioned beneath a statue of Leto, the goddess of motherhood, the crime is weighted with meaning and, Ellen discovers, remarkably similar to one from a decade past.

Ellen's professional duty is to protect the child, but she's not equipped to contend with a killer. As she races to connect the dots, she knows her time is running out. And the stakes are high: if she fails, another mother is sure to make the ultimate sacrifice.
