Hero by C.F. Welburn is the fourth book in The Ashen Levels series. Balagir ends up in a war he tries to prevent.
This is the best of the books, so far. There is more action than the other books, which was an unexpected treat! I wish there was a ten star option on Goodreads, because this book deserves it! I'm surely going to miss this series when I'm done with the fifth and last book in this series. Well done, Welburn!
