When Earth is plagued by an epidemic of fear, ancient prophecy says only Thor can stop the monstrous threat of the Serpent, but without help from Loki, Thor is certain to fail. Aided by a handmaiden from Hel and a demon puppy, Loki must risk everything to find redemption—or doom himself for eternity. Either way, a Nightmare lies in wait hoping to rule the world, and Loki will have to risk everything on his craziest scheme of all!

Meanwhile, new gods threaten to disrupt the status quo, throwing everything out of balance. Loki must act as a responsible ambassador, but will the nine worlds end in Surtur’s fire?

In this brand-new prose novel inspired by the epic comic series by Kieron Gillen, young Loki must cross the realms to reclaim his own story, outwit ancient enemies, struggle to do the right thing, and avoid falling in love.
