Rebecca by Daphne du Maurier

The novel begins in Monte Carlo, where our heroine is swept off her feet by the dashing widower Maxim de Winter and his sudden proposal of marriage. Orphaned and working as a lady's maid, she can barely believe her luck. It is only when they arrive at his massive country estate that she realizes how large a shadow his late wife will cast over their lives--presenting her with a lingering evil that threatens to destroy their marriage from beyond the grave. First published in 1938, this classic gothic novel is such a compelling read that it won the Anthony Award for Best Novel of the Century.
