For three months only according to this post on Reddit... https://www.reddit.com/r/litrpg/comments/6ll8ou/fyi_delvers_llc_both_books_on_kindle_unlimited/ His books... https://www.amazon.com/Blaise-Corvin/e/B01LYK8VG5/
Oh thank you for the heads up! I've had his sequel to Delvers LLC on my wishlist since it came out, but hemmed and hawed and ended up reading other stuff hoping it would go free promo for a few days or to KU. Some books you can wait on, others you can't. It's different for everyone ^.^ Now I can check it out and save some $$$, yay!
Which is nice, but I really struggle with the why behind authors and KU. It has been debated in various places, but as an author I love it, as a reader I love it. Maybe I am just LOVE.
KU is great for beginner writers. It's given me a chance to earn my living from writing while learning my craft. Well, until I fell into the market side of things earlier this year. I'm liking the extra time to make my next few books really shine, though. Some people aren't in KU because they want to hit USA Today or NY Times best seller lists (you have to be wide to do this)... Others like the ability to be able to share their work free anywhere without the restrictions of KU. As for myself, I'm still all in KU for the time being. Speaking of Blaise, he gave me permission to post the MMORPG.com link to the Society today. Yay. That crazy cat costume!
