Natalie King has been hired to do a psychiatric evaluation for the children's court. A custody dispute. Not her usual territory, but now that she's pregnant she's happy to do a simple consult. Turns out Jenna and Malik's break-up is anything but simple. He claims she's crazy and compulsive; she claims he's been abusing their daughter Chelsea. But what if all the claims are true? Or none? How can Natalie protect the child? And how does she work out where her concerns for Chelsea slide into her growing obsession with her own lost father? More urgently: with both parents saying they're desperate to keep their daughter safe - what if one of them is desperate enough to kill?
