Rather than keep listing books one by one I'll share my method for getting free books from Amazon. In the Amazon search box type in "free kindle books" this will bring up a list of over four hundred free books. Everything from classics to not very good books or the wonderful books that authors offer for free to get their readers interested in a series.
If you want to narrow your search down try searching for "free kindle books romance" or "free kindle books mystery". You get the idea.
Take the time this holiday season to relax with a book that didn't strain your budget. Hey, if it's lousy you can always delete it without a care.
P.S. Oh, and don't forget the library. Ours not only offers traditional books and dvds, but has an increasing amount of ebooks available.
