The continuing adventures of Christopher Sinclair, mechanical engineer turned priest of war. Christopher, raised from the dead and promoted to a moderate rank, takes command of the army regiment he trained and equipped. Sent south to an allegedly easy posting, he finds himself in the way of several thousand rabid dog-men. Guns and fortifications turn back the horde, but Christopher has other problems that cannot be solved with mere firepower: a wicked assassin; hostile clergymen; dubious allies including a bard, Lalania, with a connection to a mysterious group of scholars; and worst of all his own impolitic tongue. But all of these pale into mere distractions once he discovers the true enemy: an invisible, mind-eating horror who plays the kingdom like a puppet-master’s stage. Lalania claims she can help—but will it be enough?
