Fiona is invisible, and her dad - an infamous crime lord - will stop at nothing to control her power.

High school is hard when you're invisible.

Fiona McClean hates her family, has had to move to a new school and seems to be completely invisible to the boy she likes. So far so normal, right? But Fiona really is invisible. She doesn't even know what colour her own hair is.

Born into a world where Cold War anti-radiation pills have caused genetic mutations, Fiona is forced to work for her mind-controlling mobster father as the world's most effective thief. When her father announces she must become a murdering assassin, Fiona and her telekinetic mother make a break for freedom. Running to a small Arizonian town, Fiona finds that playing at 'normal life' with a mother on the edge, a brother she can't trust, and a boy who drives her crazy is as impossible as escaping her father.

ABOUT THE AUTHORNatalie Whipple, sadly, does not have any cool mutations like her characters. Unless you count the ability to watch anime and Korean dramas for hours on end. Or her uncanny knack for sushi consumption. She currently lives in Utah with her husband and three kids. Follow Natalie at betweenfactandfiction.blogspot.co.uk or on Twitter: @nataliewhipple
