A Stranger in the House (Sweet Valley High)

When Ned Wakefield learns that John Marin, man he sent to jail for murder, is out, he's gripped by fear. He'll never forget Marin's last words: "I'll get you, Wakefield. Your precious little girls will never be safe again."

Ned hires a private detective to keep an eye on Jessica and Elizabeth, and cautions his daughters be alert to strangers. But then Elizabeth meets Ben, a young novelist, and Jessica meets Scott, a gorgeous television intern. Forgetting their father's warning, they fall right into Marin's deadly trap. Can Ned rescue the twins -- or will they be John Marin's next victim?
