This is a slightly odd grab-bag of stuff. It’s got three proper short stories, one thirty page deleted sequence from one of the books, several things that I can only describe as “scenes”, and some “myth” recounts. None of these pieces would make much sense to somebody who hasn’t already read all the Paksenarrion books.
I found the “scenes” to be, er, not thrilling — most of this was originally published on Moon’s blog, and I can totally see these things making sense in that context. But two of the short stories were properly exciting, but most of all it just made me want to go back and re-read the original Paksenarrion trilogy.
