Oh boy, a nice list of free books to choose from!
Note: If you are reading this on your Kindle and want to get a book from the Kindle store now, type the title with your Kindle, then toggle your 5-way switch to the right until the word store is highlighted. Press in on it to search. When the title comes up, use the 5-way toggle switch to move around the book info area to read more about the book. Make sure it is still free (or an acceptable price) before finally pressing in on the 5-way switch to "buy" it. You can always press the back button (before you press buy) if you change your mind.
And remember... what is FREE today may not be FREE tomorrow, so get it while you can!
