Dark Horizons, By Dan Smith

Dan Smith's thriller is a riff on the Lord of the Flies story of an isolated group of young people devolving into a bloody and murderous chaos, and while it contains few surprises, it is interesting enough to keep you turning the pages.

Alex's mother has recently died and he's travelling the world to forget himself. A bus crash in Sumatra leaves him injured and shaken, and so he easily follows the beautiful Australian girl Domino when she leads him to her hippy, druggy commune deep in the forest. But the accidental death of a young man in the camp finally raises Alex's suspicions (he is a little slow on the uptake) and he soon finds himself fighting for his life. A better class of thriller.
