Mia is holding her family together. She's never known her father, her mother is suffering from manic depression which she refuses to seek help for, and her twin brother Jamie is causingher real concern. So when the fire alarm is set off at school and rumours fly around that there's a pupil with a gun on the loose, she starts to worry that Jamie has done the unthinkable. Ignoring all common sense, she desperately tries to see for herself whether he could be the one with the gun…gun...
I have to be honest, I thought the plot here was a little far-fetched when reading the summary on the back of the book. I thought Mia immediately suspecting Jamie of being the gunman was a little bit of a stretch – but when reading the flashback sequences, in which Mia describes the problems encountered by anyone who Jamie saw or heard causing problems for her, it becomes completely believable that she'd be afraid he'd taken matters this far.
