Kobo has some, but doesn't make them easy to find. It's a note on the bottom of each store page instead of something you can search by. I have no idea why; if I could find the good books with no DRM I'd have spent way more money there.

Recently discovered that Brandon Sanderson's books are among the DRM free (Mistborn, Stormlight Archive, others), which is a great set of reads for fantasy fans.
