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.

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.

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.

In this short story collection of courage, adventure, and magic, heroes—ordinary people who do the right thing—bravely step forward. But running toward danger might cost them everything.

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....

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.

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.

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.

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.

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.

Thanks to his relationship with the ancient Druid Atticus O'Sullivan, Oberon the Irish wolfhound knows trouble when he smells it - and furthermore, he knows he can handle it. When he discovers that a prizewinning poodle has been abducted in Eugene, Oregon, he learns that it's part of a rash of hound abductions all over the Pacific Northwest. Since the police aren't too worried about dogs they assume have run away, Oberon knows it's up to him to track down those hounds and reunite them with their humans. For justice! And gravy!

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.

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.
