I belong to librarything.com. They have a new Early Reviewers list of books every month. You request the books you are interested in and get free books to review.
I was lucky to get a free book last month called Department 19. Today I received Umpire In A Skirt, The Amanda Clement Story.
You can find it here:
This is a great children's book. I really enjoyed it. I had never heard of Amanda Clement before but the book definitely makes me want to learn more about her.
