Morgarten (Book 2 of The Forest Knights)
Leopold of Habsburg assembles the ultimate punitive force, boasting thousands of the best knights and soldiers the Holy Roman Empire has to offer. Noll's rebel army of boys and old men have few swords, and even less armor. But he has two things that Leopold does not: a Priestess of the Weave, and a ferryman. The forests can protect them no longer. It is time to make a stand.
