The Centaur — Brendan Carroll

The Knight of Death is forced into a secret alliance with Abaddon, the Destroyer in his quest to rid the world of the Great and Horrible Queen of Babylon. Though the plan is a good one, the timing is terrible. The entire world is threatened with destruction from above as an errant celestial body takes aim at earth. Mark's mortal doppelganger places himself in grave danger attempting to divert the worldwide disaster from harming his precious Sophia. Meanwhile, the rest of the Order and half the remaining powers in the world are disagreeing loudly about what should be done with the Ark of the Covenant. On top of everything, an unscrupulous Vatican official is working a plan which will place him at the top of the Papal See and give him the power he craves to rule the world from Rome.
Lemarik uses an Old Testament method for defeating the impending flood, the angelic warriors release their human comrades into even worse danger, the Tuathan healer lands in a world of trouble and even Abaddon cannot escape a terrible fate when he tries to befriend the Queen Mother in her lair.
