A Prelude to War

After an old friend is murdered in retaliation for his mercenary strikes against the oldest vampires in the world, Atticus O'Sullivan must solicit the aid of another old friend in Ethiopia if he's going to have a chance of finishing a war he never wanted. Meanwhile, Granuaile MacTiernan starts a private war of her own against Loki, the lord of lies, and if it brings Ragnarok early—so be it.
