There is a flood of free books appearing in the Kindle store this morning and I recognize many of them as independently published books that are free over on Smashwords. As of my last count, there are now 58 of them on the free book list, that you can find
HERE. I started seeing the new books around page seven, but you may want to just skim the other pages to see if I missed one. Also, some of the books will show a price, such as $0.99 in the search list. But once you click on the book, it will actually be free (at least in the US). If it isn't, wait a few minutes and refresh the page (press F5); I know the Repairman Jack story first appeared for 99 cents, but was free only moments later.
