Here's one from my backlog of read books. The Serpent's Tale is a sequel to the unexciting but well-executed Mistress of the Art of Death, which is essential Crusaders'-era England plus C.S.I. The sequel piles on more Gumpification* and makes the protagonist a single mother, which merits only an eye roll from this quarter. I hope the series stops here, although the market for Diana Gabaldon and Sue Grafton means that the author is probably sitting on a gold mine. Not recommended.
* The phenomenon of having the protagonist interact with a inordinate number of prominent personages in a piece of historical fiction.
