I've recently joined paperbackswap.com. I love it. It is such a treat to get a new book in the mail - and fun posting my books to others, knowing they will read and enjoy them. I just finished the first book that arrived. Aunt Dimity's Death - the first in the cozy mystery series I love so much but could only find books 3-8 at the library. Finally reading book one was a joy and answered so many questions.
If you love to read, but find your bookshelf a bit crowded consider signing up and share your books with other book lovers.
