The Reckoning — Sarah Pinborough

They were children then, in that magical summer so long ago when Robert, Carrie-Anne, and Jason first met Gina. It was a summer of fun, of friendship, and of discoveries--including the discovery of Gina's strange abilities. But it all ended in a moment of madness and blood.

Now, twenty years later, Robert is still haunted by nightmares of that time. He has returned to his small hometown to confront his past and reclaim his life, but his homecoming is far from happy. Gina moved away long ago. Jason is bitter and resentful. And Carrie-Anne is about to commit an act that will horrify them all. Something unexplainable has infected the town. Could the secret lie in the past, in Gina's old house, abandoned long ago but never quite empty?
