A Sturm Is Coming. Musket Man Chronicles, #1

Many feel that the Laws of Wotan clearly prohibit the use of muskets in combat, but that didn't prevent the Empire of Anjou from introducing them and transforming the face of warfare forever. Now, a full generation after the heretical weapons drove the High Kingdom of Kriegsturm firmly onto the defensive, neither side is yet using the gun to its full potential. That's about to change. Lieutenant Marshal Sturm, one of a handful of survivors of a battalion decimated by the musket-hating doctrine of his superiors, has developed a new tactic that could flip the battlefield upside down.
The only thing standing in his way are the officers of his own chain of command. But the Empire is set to invade Kriegsturm again and the only thing that can prevent total annihilation is Sturm and his Musket Men. This volume contains the novels Sturm Warning, Sturm Front, and Sturm Shelter.
