Millie Sanders works aboard a cruise ship and has a knack for stumbling into trouble. The setting gives the books a contained, almost locked-room quality, since the suspects are all on board and the ship itself becomes a character.
Over 26 books, Millie moves up through the ranks and her personal life develops alongside the mysteries. The series is fun and fast-moving, with enough variety in ports of call and shipboard drama to keep the setting fresh.
