Into the darkness - V. C. Andrews

As lovely as one of the precious gems at her parents' jewellery store, Amber Taylor is shy and introspective - qualities misread by others as being stuck-up and superior. Facing a long, lonely summer working at the family shop, Amber's world lights up when the Matthews family suddenly moves in to the house next door, a property that has stood neglected for the longest time. And when she meets Brayden Matthews, an only child just like her, Amber soon becomes infatuated with this handsome, quirky young man who seems to know her innermost feelings almost before she does, who takes her places she never knew existed in her small town. Their connection is electrifying, unlike anything Amber's felt before. But as quickly as he appears, Brayden vanishes into the darkness. And finding out the truth about him will push Amber Taylor to the edge of madness. . .
