As of this weekend, Athenian Steel, Roman Annihilation, and Spartan Beast are entered into Amazon's Kindle Unlimited program, making them FREE to read for KU subscribers. Sadly, that also means that they are unavailable at iBooks, Kobo, & BN for the time being. I'd love for everyone to have access, no matter what their preferred store, but the reality is that sales in those outlets had been lackluster for a while.
Amazon exclusivity also means that I can't give away the Roman Annihilation novella as a freebie anymore. If you have an edition of Athenian Steel that contains that offer and run into an expired link, I apologize! To make up for it, Roman Annihilation will be free at least one time per month on Amazon, and I'll announce it via my mailing list.
Sorry again for any inconvenience caused. If you're a Kindle Unlimited subscriber, go borrow!
