Atticus O'Sullivan is the last of the ancient druids. He has been on the run for more than two thousand years and he's tired of it. The Irish gods who want to kill him are after an enchanted sword he stole in a first-century battle, and when they find him managing an occult bookshop in Tempe, Arizona, Atticus doesn't want to uproot his life again. He just wants everything to end one way or another, but preferably the way in which he can continue to enjoy fish and chips.
