'There are girl ghosts,' said Marion. 'They're called quicksilvers. Like mercury.'
'Don't you ever want to smash things?' said Marion. 'That's what quicksilvers do. Girl poltergeists.' A girl poltergeist. Thinh liked the idea - the idea of having a ghost that could break things and interfere with other people. For Thinh, Viviane, Marion and Becky, Q is their shared secret, an outlet for the monotony of school life and the pressures at home. Q wreaks all sorts of havoc - writes phoney love letters, makes prank calls, floods school toilets. She leaves a trail of chaos where ever she goes - not to mention her trademark 'Q' on windows and mirrors. But Q can't help you when your parents break up, you start failing at school, and no one cares about you, or your problems. In fact, sometimes Q only makes things worse - much worse.'
