I just finished the 6th Light Novel for Hai to Gensou no Grimgar. They're translated and available for download onto a kindle from Amazon. Or you could pirate the first 4.
God damn, this book series is great. So much better than the anime. I read the first and second books, then tried re-watching the anime. Oh man, it's so bad. I've become a book purist. He's such a good writer though.
It also ends a little different than the Anime did. That fight with Deathspots was nothing like the book version. Plus, it makes the main character seem stronger than he is. He isn't strong, and he knows it. He just has good instincts, and gets lucky from time to time.
I've also read the first 6 light novels of Sword Art Online. The 6th one takes me to the end of the Gun Grave story arc, but I still have the next 2 to read to finish the second season of Anime. I'm going to pause for now and focus on DanMachi, just because I love the Anime that much. The first season, at least. I want to know what happens.
These light novels are pretty damn good, and I like that people have translated them and made them readable on the Kindle.
