Working as a dedicated forensic psychiatrist for many years, Emma is not shocked so easily. Then she is assigned to work with Connie, a wife and mother accused of a despicable crime. Connie is suffering from dissociative amnesia—or at least seems to be.

Now it is up to Emma to decide whether Connie can stand trial for her sins. But there is something about Connie that inexorably pulls Emma into her orbit. Perhaps it is the way she seems to see right through Emma, speaking to Emma’s deepest insecurities about her life, marriage, and her own tragic past. And soon Emma begins to understand how Connie’s complicated marriage and toxic relationship with her beautiful best friend, Ness, could have driven Connie to snap—or maybe, like Connie, Emma is simply getting too close to a woman who is unforgivable.
