Sixteen-year-old Sally Dahl is a rare, modern-day Norse Witch with more power than she realizes. Playing sick from school in Portland, she’s casting rune spells during a rare astronomical convergence to bring about a better, happier planet — and hoping her parents don’t find out.
What Sally doesn’t know is that the Norse gods are still around, albeit without their divine powers — Odin is a high school principal, and blustering Thor is about to lose yet another job as a photocopier repairman. But Heimdall has the perfect cover as a forest ranger while he and his kin hunt for the newly reincarnated World Tree and try to prevent Ragnarok, the literal end of the world that could be timed to the same alignment of stars.
Instead, Sally stumbles across Managarm the Moon Dog, a lost god who seems desperate for her magickal help. But does he really share Sally’s vision of a more peaceful world, or are his intentions much, much darker? And what can she do about the ancient Berserker warriors she accidentally calls up, who pledge their allegiance and then demand junk food runs to Voodoo Doughnut and Burgerville?
