Some among the undead feel that now is the time, in the midst of human complacency, to strike against the mortals, and those in the Catholic Church also feel ready to strike against "evil," with just as little regard for the cost to human life. The power to stave this ultimate, destructive conflict between evil and righteousness rests in two wise and powerful undead brothers. But the only problem is they haven't spoken to each other in a hundred and fifty years.

Reunited under the direst of circumstances, the undead brothers Ein and Leroux DeLaLune rush to get the rest of the immortals out of Paris and away from the pagan magic of the witch Elizabeth Bathory.

The Order, under the draconian leadership of Cardinal LaCroix, closes in on Paris to exterminate the undead, and with them is the powerful lunatic Peter Stubbe. But a link between LaCroix and the Brothers DeLaLune might have a deeper effect on the outcome of the looming battle than the scores of soldiers on both sides ready to fight. Elizabeth and Leroux have a lot to talk about, and now that Dahlia knows Ein's secret, will she still love him?
