NetGalley is a book review website. You sign up, select books and then can be chosen to review a book. The more books you review, the more you will get. Sometimes you will even get 'auto approval' for a certain publisher, and then automatically can get one of their books.
The only downside, tho not much of one, is that they only allow access to ebooks. However, some publishers will contact you directly and offer to send you a hard copy.
A great website for book lovers!
