April Shadows: Virginia Andrews

Book I in the Shadows series. April has always felt like an outsider. Her older sister Brenda is tall, athletic and self-assured. April's short, sensitive and overweight and she can't bounce back from her father's criticisms the way Brenda can. She doesn't know why her formerly loving Dad has turned into a cold-hearted monster and she hates the way his cruelty is tearing their mother apart. Then Brenda brings home a college roommate: Beautiful, bewitching Celia - and April wonders if she is so very different from Brenda after all.
