This site (A Writer's Work) was started by some romance and mystery authors:
http://www.awriterswork.com/
The books include previously published books as well as new books.The authors include Nicole Byrd, Jasmine Cresswell, Kathy Lynn Emerson (historical mysteries), Lori Handeland, Patricia Rice, and others. I've heard of most of the authors on this list.
On top of that, no DRM! (They offer ePub and PDF.) And the prices look good. About the only downside I see is that this is one of those sites that e-mails you a link to the download and then only gives you three days to download it. Aargh!
