I like the idea. Maybe even have a link to each review area on the books sale page. Being in books section, so only book owners can review, but others can read. Then you can read it and see what the go is/ general consensus/ Have a poll for score/ whether people thought it was great (granted, 1-10 scores are usually terrible and it's usually 6-10 used, with 6 being bad, and 10 being amazing. 1-5 same deal happens, 3 is usually bad, and 5 is amazing)
