Out of Circulation - A Village Library Mystery, #11

In the sun-kissed haven of Charleston, Ann and Grayson race to solve a deadly puzzle before more than just books are out of circulation. When Ann's former college roommate becomes engaged, it's back to Charleston for Ann and Grayson. Before leaving, however, Ann's boss tasks her with meeting with the SC state archaeologist to help him implement a historical preservation initiative he wants the library involved with. Charleston is another fun blur of restaurants, shopping, and beach trips.
But when Ann takes a break from the fun for her meeting, she finds the state archeologist...dead. Things seem even worse when her friend's fiancé becomes a suspect in the mysterious death. Can Ann and Grayson track down the killer before someone else is out of circulation?
