From their website:
Online Novels contains the titles of more than 500 online books written by both published and unpublished authors who have made their work freely available on the internet. The novels listed here are organized by category, with brief descriptions taken from the websites on which they can be found.
Be sure to check out the listings identified in red as "Limited Time." These are books being offered as promotions, often by major publishing houses such as Random House and Harper Collins.
I have no affiliation with this website. Looks interesting, though. Looks like they're supposed to be LEGAL, but let me (or another moderator) know if there's a problem with any of the titles.
