Look for Me by Moonlight

Look for Me by Moonlight is Mary Downing Hahn's eerie, suspenseful tale of
dangerous love.
In a remote Maine inn, where Cynda is supposed to be reconnecting with her father and his new family, she is also falling in love for the first time. But this isn't a typical teenage romance. The object of her affection, Vincent Morthanos, is older and worldly, with pale, aristocratic good looks. And he has a secret—a secret that could destroy Cynda's family, unless she can free herself from love's deadly embrace.
