Soph Kowalski arrives in her new neighbourhood looking for a fresh start for her young family, and neighbours she can befriend over their white picket fences. Her husband Mike has finally quit his less-than-legal job putting bad people into the ground, and at last they can lead a normal life. But that dream threatens to explode before it's even begun when Soph and Mike learn there's a hit out on the school's queen bee. Lauren's killer body and circle of devotees might be to die for, but who would actually want her dead? There's no way Soph can let this happen - but trying to stop a murder is about to land her in the middle of the neighbourhood's darkest secret, and soon she'll discover that these picket fences can be sharp as knives . . .
