Here's the link to a site that lists quite a few new ebook publications. The listings are a combination of ebooks available for a minimum price and quite a few free. But all are DRM-free. The site does not contain the actual downloads, you have to link to the authors' sites where you can get the downloads.
The link is:

There are a few special free downloads for a limited time, among them are The Surgeon by Tess Gerritsen, available till the 23rd, and The Message Stick by Laine Cunningham, set in aboriginal Australia, available till the 20th.
Also has The Catholic Orangemen of Togo, a non-fiction account of recent history in Africa by Craig Murray.
The mix of books and categories on this site is quite diverse.
