Necromancer is such an ugly word, but it's a title Eric Carter is stuck with. He sees ghosts, talks to the dead. He's turned it into a lucrative career putting troublesome spirits to rest, sometimes taking on even more dangerous things. For a fee, of course. When he left LA fifteen years ago, he thought he'd never go back. Too many bad memories. Too many people trying to kill him. But now his sister's been brutally murdered and Carter wants to find out why.

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.

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.

Atticus O’Sullivan, last of the Druids, doesn’t care much for witches. Still, he’s about to make nice with the local coven by signing a mutually beneficial nonaggression treaty - when suddenly the witch population in modern-day Tempe, Arizona, quadruples overnight. And the new girls are not just bad, they’re badasses with a dark history on the German side of World War II.
