Synopsis
Holly's super hearing is brought into play when her older brother, Kian, lands in big trouble.
A psycho-seldom and very precious tiger figure from 1968 has disappeared from the super hero store, Hidden Heroes - and Kian gets the blame. But Kian has disappeared, just like the figure, and soon Holly and her two heroic friends, Magnus and Jose, are deeply entangled in a complex fraud case involving precious antiques and key players all over town. Someone has come up with a mean and profitable trick. But who? And why? The three friends need to investigate the world of the super nerds to solve the mystery and they need all their usual courage to do so.
The books about the hearing-impaired Holly touch upon the sense of feeling like an outsider, but also the strength in discovering that it can be an asset not to be like everyone else.
