Amazon needs reviewers to look at the finalists in its Amazon breakthrough novel contest. If you have time to do at least 25 reviews of novel excerpts, you'll be entered in a contest to win a Kindle ereader, a $2000 Amazon.com gift card, and a HP printer/fax/scanner/copier.
See the offical rules for details. The excerpts are free and up to about 5,000 words long. They will also be judging the quality of the reviews, not just the number finished.
