Reddit reviews Children of Steel

My recommendation would be: Exile's Return

Rick Griffin has also done a short or two.

If you want to go old school, Sholan Alliance series is a good choice

For free stuff, I would check out Sunset of Furmankind by Ted R. Blasingame If you dont mind simpler writing Blue Horizon is also worth a look at.

I could look though my physical books and likely come up with a few more, but there isn't a whole lot of scifi.

Edit: A few more:
Otters in space, it is a bit better then the title suggest.

John Van Stry used to write stuff. Not to fond of his current model, and hes not really targeting furs anymore.

On a little different note, its worth mentioning the deathless series when talking about Audio Books. Its not really targeted at furries, but its a post-apocalyptic tongue in cheek scifi/horror that starts out with "No such thing as werewolves"

I may read to much.
