Exploring the Kobo store I've discovered another publisher exclusively using EPUB2 (DRM-Free) books!
Our Pack Press offers a collection of serial cliff-hangers in popular genres. Individual books seem to go for $0.99, collections of early episodes are offered, but best of all the first book in each series is free! I haven't read any of these yet, so I can't vouch for quality, but the covers are well-executed.
Here are links to the freebies. You'll be able to tell by the titles which genre flavor you'll be getting:

I'd love to hear from someone who has read any of these. Are they worth the time?
