how does connor change 'throughout a monster calls'?

I can't write an essay for you but can give a general response. Conor is the novel's protagonist and point-of-view character. At thirteen, Conor is haunted by a dream in which his terminally ill mother's hands slip from his grasp. He is also the victim of bullying at school. Prone to anger and isolation, Conor learns with the monster's help to accept the unfair reality of his mother's impending death.
