I came across these books whilst commuting to school for yet another exam this morning.
Apparently it is a ‘guerilla’ campaign to try and get more people into reading again. The organisation behind it invites finders of the books to take one with them and to read it. Afterwards they would like the reader to leave the book for someone else so that it gets read over and over.
The sticker on the book says: What you have before you is a special book. It has been left to be found and read, by you! Consider it as a gift. It would be nice if you would pass the book on to someone else to teas after you have finished it. If you go to he site and enter the unique code for this book, you can finder who read the book before, what they thought of it and where they travelled with it.
