It's funny, has good characters, and good action. You don't need to know about the other discworld books to understand this one. The narration is well paced and captures the humor well. The only trouble is that the narrator runs out of unique voices, and starts making them nasally.
Practically Pratchett-Perfect in every way. Time we met an Igorina, too. Satisfying to the socks;)
I am not listening to the books in order, but it is not necessary. You meet the same characters as meeting old friends, happy to know what's going on with them at the moment...
Terry Pratchett was (and because we all read his books still is) a great genius.
Reader was fantastic, as usual, but feel a female read would have served this particular book -- and its narrator -- better.
I love this book, girls going off to war pretending to be boys has been done before but Pratchett comes at it from new angles.
