The Cannons of Merryland - Demon Land, #2

Taking place during the cataclysmic events from the end of The Struggle, Splinter's older brother, Shatter, and his squadron of Ghoul Troopers, the Corrupters, are deep behind enemy lines in the final stages of the invasion of Merryland, marching on Fort Sunstrike, which is heavily defended by a battery of relentless cannons. The fortress is the last bastion of the battered country, and the defenders will stop at nothing to protect it.
The Ghoul Troopers, elite soldiers of the Empire of Apollyon, give much of themselves to serve Demon Land, but will it be enough to crush the angelic champion of Fort Sunstrike?
