I've been poor lately and having to re-read books to hold myself over. This is one of my favorite series and the first 3 books are great. It's one of those "alt-history" series that basically asks the question; What if we lost the last 500 years of tech? Gunpowder, electricity, steam engines, and most modern technologies disappear in a instant and the survivors of a changed world have to live in the "old way".
I've been trying to get snowy to read this series for awhile. It takes place in the town she lives in and the college she attends. She would laugh her ass off at what the do to their beaver mascot in a neo-feudal world.
