A SUNDAY TIMES BESTSELLER''Irreverently funny ... kept me giggling all week.'' Scotland on Sunday"Do you have a list of your books, or do I just have to stare at them?"Shaun Bythell is the owner of The Bookshop in Wigtown, Scotland. With more than a mile of shelving, real log fires in the shop and the sea lapping nearby, the shop should be an idyll for bookworms. Unfortunately, Shaun also has to contend with bizarre requests from people who don''t understand what a shop is, home invasions during the Wigtown Book Festival and Granny, his neurotic Italian assistant who likes digging for river mud to make poultices.
