1633 by Eric Flint & David Weber (Ring of Fire 2)

Just finished 1633. Now I will sleep, tell you more about it after I wake up again. I apearently didn’t wake up until December.

This is the first collaboration work in the 1632 universe. It deals with Cardinal Richileu’s attempt to stop and control the threat from the Grantville Up-timers and Gustavus Adolphus. The Dutch Republic nearly falls.
