Eric Flint is the author of the series, though he generally prefers co-writing, so 1632 is Flint, 1633 is Flint and David Weber, 1634: The Galileo Affair by Flint and Andrew Dennis, 1634: The Ram Rebellion by Flint and Virginia DeMarce, and several short story sets (Ring of Fire and the Grantville Gazettes) edited by Flint.

You can read the entire text of 1632 (legally!) at www.baen.com/library/067...71319728.htm . I have the utmost respect for Baen, because they do this for a lot of their books, so I prefer to buy hardcopy from them whenever possible, but it's a good way to find if the book looks interesting to you.

The main premise is this: A small West Virginia mining town is suddenly transplanted into Thuringia, Germany, in the year 1631, at the height of the Thirty Years' War. Hijinks ensue (and by 'hijinks', I mean 'interesting alternate-history stuff based on the use of modern knowledge during interactions with major players in seventeenth century Europe, and just the interactions between modern personalities and those same major players: people like Gustavus Adolphus, Mazarini, Cardinal Richelieu, Count Tilly, Oliver Cromwell, Wallenstein, and so on').
