Petra Brightshade manages to get the human part of her restored. Awesome. If only everything else didn't go to hell at the same time. Apparently, she's a magnet for angry psychos. Go figure.
Chased out of her own city and on the run, Petra's got to make a choice. One, do a ritual to undo her spell, take away her humanity and restore her invulnerability, thereby rendering the aforementioned angry psycho's quest to kill her null and void. Which sounds great and all, except for it means watching the future she wants with her boyfriend Logan Gray go up in smoke.
Or two, do nothing and keep fighting against an adversary she can't kill.
