The Mongol's Coffin - Paperback

They used to be part of a special ops intelligence group known only as the Unit--until the brass decided to ignore their intel, and they followed Lieutenant Grant Casey into a firestorm to save a museum, and the people trapped inside. The aftermath leaves Grant and his wingman in the hospital, and the whole team on the outs with the military. But Grant fuses his interest in history with his specialized training, and the Bone Guard is born.

The Bone Guard. . .where adventure and history ignite.
