The Bones of Haven

As peace talks proceed between the Low Kingdoms and the country of Outremer, Hawk and Fisher are assigned to work with the Guards SWAT (Special Wizardry And Tactics) team to stop a riot in Haven's largest prison. The riot turns out to be a cover for something much more elaborate and dangerous, involving a renegade sorcerer, a terrorist who will stop at nothing to undermine the peace negotiations, and an ancient magical secret.
