Amazon knows when I finish reading books

Recommendation systems are in wide use today, and Amazon's website is a prime example of that use.  In addition to the recommendations on the site, whenever I buy a new Kindle book, I receive emails with recommendations for other items I would be interested in. The recommendations are usually spot-on, and I end up buying more Kindle books, and the cycle continues.

Recently I noticed that whenever I finish a Kindle book, Amazon sends me an email with related books that I might be interested in, which is pretty cool if you ignore the fact that an algorithm is watching when you finish a book, and triggers a recommendation email to entice you to read more.

The feature might have been in place for some time, and I might not have noticed it, were it not for a very long book that I was reading on and off over the last year. After I was done, I received an email recommendation for other books by the same author, equally as long. Even though the recommendations are good, I am sure I am not going to buy these books any time soon.
