For someone who’s been alive for two thousand years, Atticus O’Sullivan is a pretty fast runner. Good thing, because he’s being chased by not one but two goddesses of the hunt—Artemis and Diana—for messing with one of their own. Dodging their slings and arrows, Atticus, Granuaile, and his wolfhound, Oberon, are making a mad dash across modern-day Europe to seek help from a friend of the Tuatha Dé Danann. His usual magical option of shifting planes is blocked, so instead of playing hide-and-seek, the game plan is . . . run like hell.

Cutting a deal with a trickster god rarely goes well for any human brave or foolish enough to try it, but Atticus doesn’t feel like he has a choice. With members of the Norse pantheon out for his blood, he can’t train his apprentice in peace, so he asks Coyote to help him fake his own death. The cost, however, might wind up being every bit as high as if he’d made no deal at all.

Unchained from fate, the Norse gods Loki and Hel are ready to unleash Ragnarok, a.k.a. the Apocalypse, upon the earth. They’ve made allies on the darker side of many pantheons, and there’s a globe-spanning battle brewing that ancient Druid Atticus O’Sullivan will be hardpressed to survive, much less win.

For nearly two thousand years, only one Druid has walked the Earth—Atticus O’Sullivan, the Iron Druid, whose sharp wit and sharp sword have kept him alive as he’s been pursued by a pantheon of hostile deities. Now he’s got company.

When a Druid lives as long as Atticus does, he’s bound to run afoul of a few vampires—make that legions of them. Even his former friend and legal counsel turned out to be a bloodsucking backstabber. Now the toothy troublemakers—led by power-mad pain-in-the-neck Theophilus—are no longer content to live undead and let live. Atticus needs to make a point—and drive it into a vampire’s heart.
