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. One survival strategy has worked for Atticus for more than two thousand years: stay away from the guy with the lightning bolts. But things are heating up in Atticus's home base of Tempe, Arizona. There's a vampire turf war brewing, and Russian demon hunters who call themselves the Hammers of God are running rampant. Despite multiple warnings and portents of dire consequences, Atticus and Leif journey to the Norse plain of Asgard, where they team up with a werewolf, a sorcerer, and an army of frost giants for an epic showdown against vicious Valkyries, angry gods, and the hammer-wielding Thunder Thug himself

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. With a fallen angel feasting on local high school students, a horde of Bacchants blowing in from Vegas with their special brand of deadly decadence, and a dangerously sexy Celtic goddess of fire vying for his attention, Atticus is having trouble scheduling the witch hunt. But aided by his magical sword, his neighbor's rocket-propelled grenade launcher, and his vampire attorney, Atticus is ready to sweep the town and show the witchy women they picked the wrong Druid to hex

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. Now the determined deity has tracked him down, and Atticus will need all his power — plus the help of a seductive goddess of death, his vampire and werewolf team of attorneys, a sexy bartender possessed by a Hindu witch, and some good old-fashioned luck of the Irish — to kick some Celtic arse and deliver himself from evil

For a two-thousand-year-old Druid, 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.  Crashing the pantheon marathon is the Norse god Loki. Killing Atticus is the only loose end he needs to tie up before unleashing Ragnarok—AKA the Apocalypse. Atticus and Granuaile have to outfox the Olympians and contain the god of mischief if they want to go on living—and still have a world to live in

After twelve years of secret training, Atticus O'Sullivan is finally ready to bind his apprentice, Granuaile, to the earth and double the number of Druids in the world. But on the eve of the ritual, the world that thought he was dead abruptly discovers that he's still alive, and they would much rather he return to the grave.  Having no other choice, Atticus, his trusted Irish wolfhound, Oberon, and Granuaile travel to the base of Mount Olympus, where the Roman god Bacchus is anxious to take his sworn revenge — but he'll have to get in line behind an ancient vampire, a band of dark elves, and an old god of mischief, who all seem to have KILL THE DRUID at the top of their to-do lists

Druid Atticus O’Sullivan hasn’t stayed alive for more than two millennia without a fair bit of Celtic cunning. So when vengeful thunder gods come Norse by Southwest looking for payback, Atticus, with a little help from the Navajo trickster god Coyote, lets them think that they’ve chopped up his body in the Arizona desert. But the mischievous Coyote is not above a little sleight of paw, and Atticus soon finds that he’s been duped into battling bloodthirsty desert shapeshifters called skinwalkers. Just when the Druid thinks he’s got a handle on all the duplicity, betrayal comes from an unlikely source. If Atticus survives this time, he vows he won’t be fooled again. Famous last words
