Interred with Their Bones by Jennifer Lee Carrell
This novel is thriller-meets-literary-history and a very good story. It is book #1 in the Kate Stanley series (which as far as I know only has 2 books in it so far). There was a lot of interesting Shakespeare scholarship stuff and a thrilling chase through a library to keep you turning pages.
