Amanda Quick, a pen name for Jayne Ann Krentz, can be counted upon to write historical romances set in Victorian England, usually with a twist of mystery. They are all light, a little steamy, and feature strong female characters. In sum, they are guaranteed to take you away from reality making them perfect getaway reads. They are especially enjoyable on audio because of the narrators' English accents.
