Colin Fischer - Miller, Ashley a Stentz, Zack

Colin Fischer is 14 and he has Asperger's. A lot of the world is a mystery to Colin - he can't read his classmates' expressions without looking at a chart, the colour blue is really off-putting and he has no idea why his parents like to hug him. But when a gun goes off in the school cafeteria one lunchtime, Colin knows he can work out who did it.
