In this last volume in the Infinite Games series.  all of the Marshlanders and their allies form companies to prepare for battle.  The Delta Company sets off to the farthest reaches of the southern mainland, the Dunlin Company prepares to retake the coastal farm William has inherited, and the Marshland Company journeys into the vast wetlands to find allies who have been hiding there for years.

This is a novel about war, challenging beloved communities to take one last stand against evil at the battle for the Black Fen.  It is also a novel about the messy outcomes of war, when the victors must find radically news ways to rule lest the whole cycle repeat itself.  And those ways have to do with infinite rather than finite games.
