Wars are fought on many fronts.

A battle is raging across New Colorado Protectorate with both human and demonic players. Todd and Nick Ruger are sentries with an arsenal of talents and training to combat threats from a variety of enemies.

Todd and Nick are given a mission to find and stop weapons smugglers by going undercover on the riverboat, Annabelle. These aren't typical arms dealers, they're demons and they're not afraid of a pair of sentries. The Rugers will have to use all their skills and their most powerful weapon, the bond between them, just to stay alive.

Stopping the supply of illegal weapons turns to trying, and failing, to thwart an assassination. Todd and Nick have each other, but will they be able to keep their love intact?
