If you got to Amazon.com and enter the Kindle page, up near the top is Discussions.
If you enter there is a thread which list free books daily.
Most of them are new authors and some are quite good.
Disclaimer: This is a "running" thread. The books are only free for 1 or 2 days and then it goes back to normal kindle prices. I check in everyday and pickup 2 to 6 books everyday.
If you are new to the thread just go to "newest first" at the top right and you can start perusing there.
I like the thread because several people save me countless hours by going through and labeling the genre and/or giving a brief description of the book.
I love Sci Fi, but there is Non-fiction, romances, historicals and guy stuff.
