Loki would be stunningly good-looking if not for the poison scars on his face and the pinholes lining his lips. The immortal jotun had an honorary place among the Aesir gods until he played one trick too many on the wrong crowd. Now he’s tied to a rock in an underground chamber, wasting away while a massive serpent drips venom onto his face. Yet he’s not powerless. Through magic, he manifests in visions and in mortal form, and manipulates others to further his scheme of unleashing Ragnarok. His big mistake? Underestimating Magnus Chase and friends…and not seeing a certain walnut in time.
