1635: The Cannon Law is a continuation in the increasingly complex Rig of Fire novels; a multi-limbed monster that began with 1632, where the inhabitants of a West Virginia town were hurled through time and space to end up in middle of war torn Europe in the year 1632. Things have continued to degenerate over the last three years, and now the characters from the premiere novel are scattered across Europe involved in separate books. So instead of one series of books, there are now at least three offshoots written by Eric Flint and a series of co-authors.
