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. Super-lame, right? Being a teenager is tough enough without throwing a useless power into the mix. It's silly to be scared of a girl who can phase through a salad fork with the greatest of ease. All she wants to do is put the resident mean girl in her place and convince her crush that she exists. But someone with a power like hers is popping out of mirrors to spy on local girls like a total creeper.
