On the streets of Boston, the world is divided into the ordinary Usuals, and the paranormal Unorthodox. And in the Department of Unorthodox Affairs, the Auditors are the magical elite, government-sanctioned witches with spells at their command and all the power and prestige that comes with it. Grimshaw Griswald Grimsby is…not one of those witches.

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.

Thor, the Norse god of thunder, is worse than a blowhard and a bully - he’s ruined countless lives and killed scores of innocents. After centuries, Viking vampire Leif Helgarson is ready to get his vengeance, and he’s asked his friend Atticus O’Sullivan, the last of the Druids, to help take down this Norse nightmare.

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.

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 15 years ago, he thought he'd never go back. Too many bad memories. Too many people trying to kill him.

A call from a distraught wife, and another from Lt. Murphy of the Chicago PD Special Investigation Unit makes Harry believe things are looking up, but they are about to get worse, much worse. Someone is harnessing immense supernatural forces to commit a series of grisly murders. Someone has violated the first law of magic: Thou Shalt Not Kill. Tracking that someone takes Harry into the dangerous underbelly of Chicago, from mobsters to vampires....

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.

Atticus O’Sullivan, last of the Druids, lives peacefully in Arizona, running an occult bookshop and shape-shifting in his spare time to hunt with his Irish wolfhound. His neighbors and customers think that this handsome, tattooed Irish dude is about twenty-one years old - when in actuality, he’s twenty-one centuries old. Not to mention: He draws his power from the earth, possesses a sharp wit, and wields an even sharper magical sword known as Fragarach, the Answerer. Unfortunately, a very angry Celtic god wants that sword, and he’s hounded Atticus for centuries....

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.

When he was 19, James Stark was considered to be one of the greatest natural magicians, a reputation that got him demon-snatched and sent downtown - to Hell - where he survived as a gladiator, a sideshow freak entertaining Satan's fallen angels. That was 11 years ago. Now, the hitman who goes only by Stark has escaped and is back in L.A. Armed with a fortune-telling coin, a black bone knife, and an infernal key, Stark is determined to destroy the magic circle.
