Plenty of teenagers feel invisible. Fiona McClean actually is.

An invisible girl is a priceless weapon. Fiona’s own father has been forcing her to do his dirty work for years -everything from spying on people to stealing cars to breaking into bank vaults. After 16 years, Fiona’s had enough. She and her mother flee to a small town, and for the first time in her life, Fiona feels like a normal life is within reach. But Fiona’s father isn’t giving up that easily.

Of course, he should know better than anyone: never underestimate an invisible girl.
