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.

Grimshaw Griswald Grimsby may have one case under his belt, but he’s still a novice Auditor in Boston’s Department of Unorthodox Affairs. And he’s already made mistakes. Desperate to repair his fraying friendships, he doesn’t ask too many questions when a mysterious patron offers him the chance to join a heist of an otherworldly vault—and in the process find answers that could make things right.

Since time immemorial the Spires have sheltered humanity, towering for miles over the mist-shrouded surface of the world. Within their halls aristocratic houses have ruled for generations, developing scientific marvels, fostering trade alliances, and building fleets of airships to keep the peace. Captain Grimm commands the merchant ship Predator. Fiercely loyal to Spire Albion, he has taken their side in the cold war with Spire Aurora, disrupting the enemy's shipping lines by attacking their cargo vessels.

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.

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.

Al MacBharrais is both blessed and cursed. He is blessed with an extraordinary white moustache, an appreciation for craft cocktails - and a most unique magical talent. He can cast spells with magically enchanted ink and he uses his gifts to protect our world from rogue minions of various pantheons, especially the Fae.

When marine private Oliver Chadwick Gardenier is killed in the marine barrack bombing in Beirut, somebody who might be Saint Peter gives him a choice: Go to heaven, which, while nice, might be a little boring, or return to earth. The Boss has a mission for him, and he's to look for a sign. He's a marine: He'll choose the mission. Unfortunately, the sign he's to look for is "57". Which, given the food services contract in Bethesda Hospital, creates some difficulty. Eventually it appears that God's will is for Chad to join a group called Monster Hunters International.

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.

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.

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.

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.

In the realm of Alera, where people bond with the furies - elementals of earth, air, fire, water, and metal - 15-year-old Tavi struggles with his lack of furycrafting. But when his homeland erupts in chaos - when rebels war with loyalists and furies clash with furies - Tavi's simple courage will turn the tides of war.

Davi has done this all before. She’s tried to be the hero and take down the all-powerful Dark Lord. A hundred times she’s rallied humanity and made the final charge. But the time loop always gets her in the end. Sometimes she’s killed quickly. Sometimes it takes a while. But she’s been defeated every time. This time? She’s done being the hero and done being stuck in this endless time loop. If the Dark Lord always wins, then maybe that’s who she needs to be. It’s Davi’s turn to play on the winning side.

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.
