After the Golden Age by Carrie Vaughn

pp304 by Carrie Vaughn
What can I say about this one?  It was a quick read..would be good for an airplane ride.  There was a light mystery, a lighter love story and a bit of family redemption thrown in for good measure.  Celia is the daughter of superhumans, who've spent their adult lives fighting crime as vigilante heroes.  But Celia has no powers.  After a stupid stunt in her teens, she is estranged from her parents for years until "the trial of the century" begins and Celia discovers the reason for her parents' amazing powers and eventually does her part to "save her city."  The book is listed under the FANTASY section but it would probably fit MYSTERY better or SCI-FI, maybe.
