It's a book series by John Flanagan. I think there are four books out so far. This series is just one of many that I enjoy reading. If you've read it, please tell me what you thought of it.
I love the series. It's great. There are six or seven books out as of 2006, I believe. That's in Australia though, so we have to wait or get them on Amazon. I've read 1-4 twice each at least. They're great
