I chose Wee Free Men by Terry Pratchett on a recommendation from a friend who really enjoys Terry's books. I can now see why!
The book starts out with a young girl named Tiffany. She's down by the river with her younger brother, and a monster comes out towards her. She attacks it. She also encounters these small blue men who speak kind of funny. This is when she realizes there is something different about her.
The little blue men are the Nac Mac Feegles, or as they call themselves, the Wee Free Men. They're blue, they wear kilts and they speak with a Scottish accent. I have to say, I absolutely loved reading what they were saying! It was amusing. I kept picturing little leprechauns that had defected to Scotland. And since they enjoyed drinking, they clearly had found the good Scotch ale!
Back to the story. Tiffany's little brother is abducted by the Quin, er, I mean queen, and miss Tiffany has to figure out how to get into the Queen's world to get him back. She is assisted by the Nac Mac Feegles, and has a few adventures along the way.
I really enjoyed this story, and I highly recommend it. Now that Harry Potter is over, I think this will make a great new series to read. (There are apparently several books written by Mr. Pratchett.) Let me know if you've read any of these books yourself and what you think! I'd love to compare notes!
