Mirror, mirror on the wall. Who's the biggest loser of them all? Mira Mason has the world's most useless superpower: she can pass through shiny objects. As far as powers go, it's super-lame. Being a teenager is tough enough without throwing a useless power into the mix. The world is afraid of supes, but it's silly to be scared of a girl who can phase through a salad fork with the greatest of ease. All Mira wants to do is put the resident mean girl in her place, get her powers teacher off her back, and convince her crush with the mesmerizing eyes that she exists. But someone with a power like Mira's is popping out of mirrors to spy on local girls like a total creeper. Mira just wants to be normal, but sometimes a girl and her superpowered friends have to make a stand.
