Sixth book (third in a new story arc) in the Iron Druid Chronicles series, described by SFF World as 'Neil Gaiman's American Gods meets Jim Butcher's Harry Dresden'.
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 De 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.
