Guardian of Torment

Just once, Nyx Fortuna would like something in her life to be easy...
Nyx has finally managed to dismantle the magic keeping her from her missing memories, but things are a bit...fractured. Her mind keeps slipping into different points in her past, and she's not always aware of when the present is.
The issue couldn't have come at a worse time, because she finally has a lead on the Kumir-the race of identical assassins who have hunted the Hidden to the brink of extinction-but following that lead involves another interstellar trip. Recognizing that covert operations on a foreign planet aren't a good idea with her current problems, Nyx reluctantly agrees to let her friends go without her.
But when a malfunctioning memory combines with an unintended use of portal magic, Nyx ends up right where she shouldn't be. Complications prevent her from returning to Earth, leaving Nyx to navigate an alien metropolis while hoping her skipping memory doesn't get her killed.
