Actually a fire station, not a shop. On May 20th I will be an author guest at the Firestation Book Swap, which is held regularly at the Firestation arts centre in Windsor. The hosts will be publisher Scott Pack and novelist Marie Phillips and the other guest will be the historian Kate Williams. All you have to do is turn up with a book. Any book, as long as it is interesting and you are prepared to part with it. Everyone comes with a book and goes home with a different book - that is the deal. And there are cakes and stuff as well. So, if you are around the M4 corridor on May 20th, come along. With a book.
