Loki: Mistress of Mischief (comics)

Loki reborn! When the Asgardian cycle of life begins again after Ragnarock, Thor's brother Loki comes back as...Thor's sister! Loki returns with a sense of purpose, seeking a fresh start to write her story anew. But her newest scheme could be the greatest trick she's ever pulled. What secret lies behind her female form? What dread endgame does she have in mind for Thor...and for Balder the Brave? And with whom will she forge an alliance of evil? The answers may spell Asgard's doom! Years before Jane Foster soared as the Goddess of Thunder, Loki first became the mistress of mischief in these epic tales from J. Michael Straczynski and Olivier Coipel's legendary run!
