A rather mad-cap send up of the classic gothic romance by Elizabeth Peters, made even more amusing by the fact that Elizabeth Peters actually wrote classic gothic romance under the pen name Barbara Michaels. At times it veered into farce, but was still more enjoyable than not.
This is a very lighthearted book, with a likeable main character, Jess, and her protector/boyfriend David who are being pursued by a pair of moderately incompetent semi-villainous villains (well, one of them is more villainous than the other). There is lots of Arthurian mockery, tripping over ruins in the moonlit darkness, and tea drinking. Cute.
