I just finished reading the first three books of the Epic of Andrasta and Rondel. I thoroughly enjoyed these books as I've enjoyed all of Joshua Simon's books to date. The plots of the books have been entertaining and the characters developed enough to not being able to fully anticipate their actions. I noticed very few editorial errors, but they never really bothered me.
The story is based upon two individuals, and based upon their current circumstances, decide to partner up. Over the course of the book, and the next two to a larger degree, their ill-fitting partnership develops into a true friendship. While they navigate their way through various adventures, their respect and appreciation for one another grows.
My only complaint is the addition of magic to the story. I never cared for magic or sorcery in the books I read, instead believing they would be stronger and more enjoyable without it. That's more of a complaint of the genre as opposed to the writer or writing itself.
I have read almost all of Joshua Simon's books, and look forward to reading his next one. A very talented writer with a great knack for story-telling.
