When Unity, Connecticut's Independence Day cannon firing ends in disaster, historian Christian Shaw finds herself in the middle of a murder case-and a land-use dispute involving a possible Revolutionary War battlefield. Worse, her new client is hanging around the Historical Society looking for ideas for a Regency romance reality show. And then she gets involved with 90-something Amy Taylor's bat mitzvah.
