The end of the rainbow - V. C. Andrews

Rain's daughter Summer is about to turn sixteen. All her life, she has lived on the Virginia family estate where the Hudson family's secrets have lurked among the shadows for generations. Like all girls her age, Summer dreams of growing up and making her own life, of falling in love and finding her soulmate.
But a devastating tragedy will force Summer to stare into the cold eyes of adulthood long before she is ready, and flee the only place she has ever called home. For Summer is about to discover secrets of her own. Some she will keep. Some she will share. And some will haunt her for the rest of her life.
