After caring for his mother in her last days, Alex has gone off round the world - with no plan other than to travel and maybe recapture some of his lost youth. Beginning his travels in Indonesia, the idea of finding himself sounds appealing...but soon, he finds himself in real trouble. It starts with a bus crash on a terrifying mountain road. Lucky to escape with his life, Alex loses everything else - even his identity. But then he meets Domino, a beautiful girl who takes Alex under her wing. At first it's an intoxicating adventure, but Alex starts to realise that danger follows her around. As they approach the magnificent Lake Toba, and head to the remote community of free spirits that Domino calls home, it seems there's trouble in paradise. The ideals of the camp seem honourable - a simple life, shared by friends in a beautiful place hidden from the world. But Domino has no answers for the questions that are forming in Alex's mind: Why do the local villagers hate them so much? Why are people leaving the camp in the dead of night? And what are the strange shapes lurking just beyond the clearing? A taut, atmospheric and emotive thriller, DARK HORIZONS transports you to the lush landscapes of Sumatra, and the twisted ideals and deadly secrets lying in wait there...
