Even better, she and her bookstore are located in Stonewall, a picturesque town nestled in the foothills of Tennessee's Blue Ridge Mountains. Unfortunately, Margaret also has a sister -- Bitsy.The morning Bitsy flings a dead pigeon on her sales counter, Margaret decides to redefine her mission in life. "Never assume anything as far as Bitsy is concerned' sound like sane words to her, and that's good, because Margaret's going to need them.
