Very much enjoy the series, Eric Flint has a ready home in our house for any book he chooses to write. 1632.org is a fan site dedicated to his series, and something you might enjoy visiting too.
I've been to the 1632.org site. Probably need to hit it again, as it's been a while.
I'm reading The Bavarian Crisis right now. You can really tell when it's Flint writing, and not DiMarce. Wish he'd do one solo again.
