Traumatized by the tragic death of a child in her care, psychotherapist Chloe Madison abandons her Manhattan practice and returns to her hometown in Vermont. She meets April, an engaging child with a unique disability: like the mythical nymph Echo, April can only speak by repeating what others say. Despite having no understanding of language, she listens to conversation the way the rest of us enjoy birdsong and talks by imitating the unintelligible words she hears. When April witnesses her father’s murder, her extraordinary talent for mimicry offers the best hope of uncovering the killer’s identity.  But first, Chloe must face the demons from her own past and reach beyond the norms of therapy to help the girl recover—and ultimately heal herself.
