These are short stories - though Snowraven is pushing towards novella length. And while I've had many novels published, they're all work-for-hire and (thus), sadly, out of print. No e-books have been issued.
On the other hand, I have plenty of work up on Smashwords (and Amazon), of varying lengths -- including Martian Knights, which is a collection of my shorts (many available singly or in small groups) and Zombies, Werewolves, & Unicorns, which contains 2 novellas.

I hope to have at least 2 new novels out this year -- one within the next month or two.
Hope that helps, Richard.
