Jack Manley and the Warlord of Infinity

Jack Manley - soldier, adventurer, traveller of the Wild Multiverse and veteran of the All-Worlds War - has quit. The Warlord - scientist, cross-time martial-arts master and interdimensional tyrant - wants him dead. Between Manley and the Warlord lies an army of beings from twelve alternate Earths: soldiers, manticores, dogs with guns in their mouths, the dreaded annihil-apes and more. The Warlord is coming, and nothing short of death can stop him. Manley has vowed never to kill again. HOW'S HE GOING TO GET OUT OF THIS ONE?
