For all of the Kindle owners out there who want free books--
They have compiled a list of hundreds of free Kindle books from Amazon. Granted, in true free book form, the majority of them are books that you've never heard of and probably wouldn't hear of otherwise. However, if you're an adventurous reader and willing to try something new (especially if it's FREE), go for it! I always keep an eye on the freebie list as there are a number of titles that do make a jump over into the mainstream...
Also, maybe the more exciting tool for those of you who aren't as adventurous--
Kindle Price Drop Tracker
Hosted by the same company, this allows you to follow titles that you're interested in and get a heads up when their prices drop! Kind of like Farewatcher for books!
p.s. Remember, you could ALWAYS just go get whatever book you want at your library!!!!!! for FREE!!
