title_body: How to view book summary on Kindle reader
upvoted_answer: Not exactly what you are looking for but maybe this will be sufficient. When you are in the library on your Kindle, to the right of the title there are three little dots. Click/touch that and then select the option that shows the book in the Amazon store. That gets you to the Amazon page with the description, reviews, etc. I just figured this out myself. I wish it was easier than that -- just gives us the "back cover" of the book.
