1635: The Tangled Web (Baen, 2009) written by Virginia DeMarce is a novel in the 1632 series. It is actually composed of four interrelated stories which involve, to one degree or another, the up-timers stationed in Fulda.
1: "Prince and Abbot", which originally appeared in a slightly different form in Grantville Gazette VIII
2: "Mail Stop", which originally appeared in a slightly different form in Grantville Gazette IX
3: "Happy Wanderer", which is essentially a continuation of "Mail Stop". It continues the story of independent courier Martin Wackernagel. In the course of the story, Wackernagel's multiple marriages are discovered and dealt with.
4: "Window of Opportunity", which provides the backstory to Duke Eberhard's decision to will Württemberg to its people. It also deals with Nils Brahe's move to take what would become the USE's Province of the Upper Rhine, as well as the fate of those responsible for the kidnappings which occurred in "Prince and Abbot".
