Ginny and Adam Trustlove arrive on holiday in Italy torn apart by personal tragedy. Two weeks in a boathouse on the edge of peaceful Lake Orta is exactly what they need to restore their faith in life - and each other. Twenty-four hours later, the silence is broken.

It doesn't take long for Ginny and Adam to be drawn in, especially when the teenage Pippi introduces a new friend into the circle. For there is something about Zach that has everyone instantly beguiled, something that loosens old secrets - and creates shocking new ones. And, yet, not one of them suspects that his arrival in their lives might be anything other than accidental . . .
