I'm now a member of BookCrossing - a team that's best described as guerilla librarians. It's really rather a beautiful system for sharing a book you've enjoyed and want to pass on. BookCrossing gives it a unique BCID Number and you then "release it into the wild" to be found by a passing stranger. Whomever finds it, like myself with this book, "Witchcraft & Black Magic" (BCID: 003-7425446) is to read it then log a record of it and it's release on the website. You can even follow my BCID to see where it has been, and where it goes!
This book (along with some of my own BCID'd novels!) will be released somewhere on my travel home to Lincolnshire in a couple of weeks, so if you're in any big train stations between Somerset and Lincolnshire, have a look round - you never know!
