What Have They Done to Liza McLean?

Meg McLean is a scholarship student at the ultra-elite Douglas College. Meg's younger sister, Liza, is along for the ride, and everything Liza has done since they arrived at the school seems to be putting their chances of success at risk.Until one day, when Liza's behaviour is so at odds with her usual temperament that Meg knows something is very, very wrong.Benedict Hargreaves (the 4th) is Douglas College's wealthiest student and perhaps the only one who isn't influenced by the school and its strict code of conduct. Is he brave enough to help Meg uncover what has happened to her sister? Or is he part of the elusive 'they' who seem to be controlling everything - and everyone?And, when more than one murder takes place, can Meg really trust anyone?
