Everybody's favorite Catholic outer-space delivery pilots return for their greatest adventure yet in Weapons of War! Fresh from saving the solar system while being introduced to God and his Church in The Truth Is Out There and defeating a lunar megalomaniac determined to rewrite salvation history in The Big Picture, Brendan and Erc land in a magnificent domed city on Mars-for what is supposed to be a simple shuttle job. But soon they find themselves caught up in a sinister assault on faith and freedom. Will Mars be lost to the Enemy? Brendan and Erc's only hope for the fight is in the power of God's sacramental gifts.
