The third book in the thrilling urban fantasy series featuring Atticus O'Sullivan -- a smart-ass, bad-ass, 2,000-year-old Druid--finds our hero embarking on his boldest adventure yet. Atticus has just rescued his town from the designs of a coven of diabolical Nazi witches (a story told in HEXED, the second book in the series), though only with the intervention of a powerful Hindu sorceress. Her price: the golden apples of Asgard, which grant eternal youth. Asgard is the home of the Norse pantheon ... including Thor, the god of thunder, who has made enemies all over the supernatural world. It seems like everyone wants Thor dead -- including Atticus, who has made a promise to his best friend, an Icelandic vampire, to take him down, in exchange for guidance through the perilous supernatural kingdom. Atticus has slain demons, outsmarted Coyote, and killed an ancient Celtic god, but he's never faced a showdown like this, with the mighty Thor himself. Will this be Atticus' last stand ... or will he rain Ragnarok down on Asgard?
