Surrounded by dense, dark woodland, The Hermitage is an exclusive girls' school. One balmy summer's night, Sukie Melville leaves her room and vanishes into the woods. The following day her body is pulled from the hungry water of the Menai Strait.

When McKenna scratches the glossy surface he uncovers a dark and dangerous ethos underpinning the school. Nothing in that hotbed of passionate, brooding resentments is what it seems, and no one can be trusted . . .
