PLEASE. Do everyone a favor and write an Amazon review if you end up reading a book (or trying to and giving up in disgust). It does not have to be much. Just tell what you think of the book. By the way, many times I have found the 1 and 2 star reviews on self published works to be far more revealing about the book than the more stellar reviews.
Most times these books are only free for a day or two, so you have to grab them while you can. Worry about whether you really want to read it later if it seems interesting. And be careful, they can change from free to not free at any time.
