Sarah Hilary, Theakston's Crime Novel of the Year winner and author of Fragile, returns with another compulsive psychological thriller, that questions how much you know about the people who live next to you. Blackthorn Ashes was meant to be their forever home. For the first six families moving into the exclusive new housing development, it was a chance to live a peaceful life on the cliffs overlooking the Cornish sea, safe in the knowledge that it had been created just for them. But six weeks later, paradise is lost. Six people are dead. And Blackthorn Ashes is left abandoned and unfinished, its dark shadows hiding all manner of secrets. One of its surviving residents, Agnes Gale, is determined to find out the truth about what happened. Even if that truth is deadlier than she could have ever believed possible.
