Cameo lives in a caged supernatural city where all species are tagged at birth with silver brands embedded in their foreheads. Her X brand identifies her as a Mixbreed, but she’s so much more. Like a chameleon, she can shift from one person’s image to another.

It’s a great way to make money for a habitat street kid, or Cage Punk as most people call them. Wiz, her street partner-in-crime, finds her jobs to use her abilities. Some jobs entail changing into people to take academic tests. Others require more skill and involve higher risk.

When Wiz asks Cameo to stand in for a Were-wolf teenager who doesn't want to go to her debutante ball, it seems like just another job, until a corpse is discovered and an old friend of Wiz appears.
