House of Secrets by V.C. Andrews

Ever since Fern could remember, she and her mother have lived as servants in Wyndemere House, the old gothic mansion of the Davenport family. She may have been a servant, but Fern developed a sweet friendship with Dr. Davenport’s son, Ryder, and she was even allowed free range of the estate. But Dr. Davenport has remarried and his new wife has very different ideas about a servant’s place. Now Fern and her mother are subject to cruel punishments, harsh conditions, and aren’t even allowed to use the front door.

Yet, for all her wrath, the cruel woman cannot break the mysterious bond between Ryder and Fern. And when Ryder invites Fern to join his friends at prom, there’s nothing Mrs. Davenport can do to stop them nor can she continue to guard the secret that haunts the women of Wyndemere—but there’s nothing she won’t try. After all, reputation is everything.
