Alex Verus is part of a world hidden in plain sight, running a magic shop in London. And while Alex's own powers aren't as showy as some mages, he does have the advantage of foreseeing the possible future-allowing him to pull off operations that have a million-to-one-chance of success. But when Alex is approached by multiple factions to crack open a relic from a long-ago mage war, he knows that whatever's inside must be beyond powerful.

Stephen Oakwood is a young man on the edge of this hidden world. He has talent and potential, but turning that potential into magical power takes money, opportunity, and training. All Stephen has is a minimum wage job and a cat. But when a chance encounter with a member of House Ashford gets him noticed by the wrong people, Stephen is thrown in the deep end. For centuries, the vast corporations and aristocratic Houses of the magical world have grown impossibly rich and influential by hoarding their knowledge.

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.

The downside to faking your own death is that people tend to get upset when they find out they’ve been had. In Atticus O’Sullivan’s case, they’re upset enough to come after him to make sure he dies for real this time. Yet he can’t remain in hiding anymore: He has to bind his apprentice, Granuaile, to the earth so that she can become the first new Druid in centuries.

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.

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.

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.

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.

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.
