As the Summer Solstice nears, who will be the next target? A dark thriller from the bestselling author of the DI Louise Blackwell series.

In a cave near Weston, potholers discover what they think are human remains. The bones are identified as belonging to Hugo Latchford, a boy who went missing a decade ago, and whose parents belonged to a quasi-religious cult masquerading as environmental activists. It's not long before rumours that he was sacrificed in a midsummer ritual resurface.

As she begins to fathom the ghoulish depths of the group's pagan beliefs, new mother Louise is profoundly disturbed by the case. And with the Summer Solstice fast approaching, she's faced with the terrifying prospect that the group might be preparing for their next sacrifice...
