Echoes in the walls

de V.C. Andrews

The daughter of a domestic worker and the son of a wealthy dynasty continue their secret romance despite family secrets and shocking betrayals. Fern and her mother live as servants in Wyndemere House, the old gothic mansion of the Davenport family. And her friendship with Dr. Davenport's son Ryder was never a problem... until they came of age. An intimate encounter following the high school prom brings the pair near-tragic consequences. But the real threat to their happiness is something no one can control: the past, and the truths that lurk there. -- adapted from jacket
