Tiffany Aching series
If you’re a firstcomer to Pratchett, then Wee Free Men is an excellent place to start; if you're an old fan, then rest assured that all of the trademark wit you've come to love is here. I found this book hillarious. I could tell you about a girl trying to become a witch, lost baby brothers, and little blue men, but it's the clever dialogue that sells this book. Oh, and the audio book is excellent too!
