Many of my dragons and angels are currently enrolled in KDP Select, which means you can read them free with a Kindle Unlimited subscription. The enrollment term ends July 22, and I’ve decided not to renew the enrollment of these books. I’ll be republishing them at all portals again on July 23.
So, you are reading the Dragonfire Novels, or the Dragons of Incendium, or the Prometheus Project in Kindle Unlimited, get those books onto your Kindles now! July 22 is coming soon. If you shop at other portals, the books will be available there again at the end of this month.
