Ruby's got a special talent for disrupting magic and it's been causing problems her entire life. When she's recruited by the Special Monsters Unit, she finally discovers a use for her ability—and gets embroiled in a supernatural mystery that might destroy the world.

Trouble is brewing in Nexus, and for some reason, they think I can stop it. Some people are born to greatness. My mother wanted to strangle me at birth. I've not had an easy life, not in a world that thrives on magic. Spells to reinforce buildings. Hexes to give you the face of a supermodel. Or so I've been told. No one can hide their true face from me, and people get ugly when they find out my presence is the reason magic shrivels and dies.

Hide all you want. I will find you. I might not wear a cape or a mask, but as an agent for the SMU—Special Monsters Unit—I am plenty heroic. Most of the time. Accidents tend to happen a lot around me since I'm what they call a null witch. Someone who basically murders magic. Sounds cool, right? Not when it causes cursed folks to explode—literally—in my face. Gross. Not to mention I hate shopping for new clothes. Still, I love my job even if it is dangerous. Other parts of my life could use some help, though.

I don't know who to trust anymore. Learning to use my power isn't all fun and games, especially with the annoying Professor X, but I have to buckle down. The monster situation in Nexus isn't getting any better. And neither is my love life. Baptiste is about to get married, and Huego, that sexy traitor, is missing. My lessons on using my ability aren't going very well, and when my teacher goes missing, I'm back to muddling around on my own—and failing miserably.
