Parallel worlds, like parallel lines, will never meet, even if continued to infinity. Co-existing worlds, however, twist and bend and very occasionally, they meet. A vicious assault in a rural Irish pub is the first in a series of increasingly bizarre events that catapult Detective Chief Inspector Seamus Brogan into a world dominated by an all-powerful and despotic church; a church which harvests the despair, pain, and soulpower of heretics for its own power and glorification. Outside a mediaeval Dublin, a massive crusader army prepares to launch an attack on Brogan's Ireland. Swords and crossbows will be no match for the weaponry of a modern army, but the power of the human soul when harvested and targeted as a weapon of war is truly mind-blowing.
