Not the best place to start with the last two Drenai books.
Legend is his best book storywise, his most legendary
It wasnt my first book, it was my third DG but it was the first that filled me which so much emotion that i felt empty at the end. The first and only fiction book to make shed some tears. Not wanna spoil why but you will see if you read it.
Im reading Drenai realese order wise i recommend you try that way and see if you like that order. I like that order cause you see DG grow as writer, hone his skills and get better and better.
