Live Free or Die
This book is useful. When the Earth is invaded by evil aliens intent on stripping us of our heavy metals, I now know how to fight back using just Maple Syrup and a Death Star I just happen to have hanging around. That's education right there. This book is delightfully not sexist compared with some of Ringo's other books, which makes me happy. It does lack strong female characters, but at least they're not being used for titillation (refer to Cally's War for an example of how this isn't always true). I enjoyed this book.
