Family storms - V. C. Andrews

Living on the streets and selling knickknacks with her destitute mother, Sasha Porter dreams of someday having a normal life, with a real house and family. But she never thought a devastating tragedy would bring her those very things: one stormy night, a speeding car veers out of control, killing her mother and badly injuring Sasha.

While in hospital, Sasha is whisked off to a fancy private suite courtesy of the wealthy Mrs Jordan March, a complete stranger who insists that Sasha come to live at her family's luxurious mansion. With nowhere to go, Sasha accepts; however she soon learns that Mrs March has never gotten over the death of her daughter Alena. Before she knows it, Sasha is using Alena's old room, sleeping in her bed and wearing her clothes. But someone will make sure that Sasha never takes Alena's place: a jealous sister dead set on making Sasha's life a living hell.
