I just finished reading one of the books I won on another blog. Yesterday I got an email that I had won another one. So far all the books I've won have been really interesting reads. I've also started using my Paperbackswap account. I've already mailed out 8 or 9 books. I've received 3 and there are 3 more on the way to me.
Once I started using the site I discovered that you can trade any book. It doesn't have to be a paperback and it doesn't have to be fiction. It's actually a really cool site and all the books I've received have been in really good condition.
