Hammered

Atticus O'Sullivan is a Druid who is two thousand years old, and he sells occult books from a shop in Tempe, Arizona. He has made promises to people the Norse god Thor has wronged, and he means to keep every one. That requires challenging the god of thunder in person.

He gathers an odd crew for the attempt. Leif Helgarson, a Viking vampire, has a score of his own to settle with Thor. A werewolf, a sorcerer and an army of frost giants complete the group, and the quest takes Atticus into the Norse realms.

Trouble waits at home too. A vampire turf war is brewing in Arizona. The Hammers of God, a zealous order of demon hunters, are after Atticus. Meanwhile the werewolves are angry that their leader has been sent off to Valhalla.

This is the third book in the Iron Druid Chronicles, after Hounded and Hexed. Irreverent humor runs alongside real danger, and the series turns darker here, with serious consequences for several of Atticus's friends. The Norse gods stay close to their mythic originals, so they are bullies and schemers rather than heroes. Atticus has to face one of them and keep his promises.
