Well, red is the color of blood.Young Thomas Fawkes's Color Test has finally arrived, and he's sure his father, the infamous Guy Fawkes, will present him with a mask and Thomas will finally bond with a color. He desperately hopes for a gray mask so he can remove the stone that has invaded his body and will ultimately take his life.But when Guy refuses to give Thomas his mask or even his presence, Thomas has no place in school or society. His only hope is to track down his father and demand a mask. His father has bigger plans: to kill the king.Thomas must join forces with Guy if he wants to save his own life. When his errands for the cause bring him time and again to Emma Areben, a former classmate, Thomas is exposed to a whole new brand of magic. And Emma doesn't control just one color--she controls them all.Emma wants to show Thomas the full power of color magic, but it goes against everything his father is fighting for.
