To celebrate, I'm going to send that 400th book around as an International Book Ray, to anyone who would like to read it. The book is a favourite of mine and a well-known classic, Jane Austen's Sense and Sensibility.
If you would like to read this book, please comment here with your name (or BookCrossing name) and the city, state and country where you reside. If you don't want to put that information here, you can send a BookCrossing PM to me at herebedragons, or you can e-mail me at email@example.com. You must be willing to ship internationally (surface mail is fine, and it's a thin paperback book - won't cost a lot to send). I will group names, though, so that postage costs will be as low as possible for as many people as possible.
So, if you'd like to celebrate my 400th book with me, just let me know! :)
