outside reading 3

I started to read Mister Monday written by Garth Nix. I only read the first 2o pages but it seems to be a lot like Harry Potter. This is because random people come from this different world that we have no idea exists. Also the main characters are alike because they are not liked by the people around them. In Harry Potter its his family while in Mister Monday its the classmates. Another connection is that the main character in both of these receives some sort of device to help them out. Although in Mister Monday all we know about this device is that it clears the main character's, Arthur Penhaligon, asthma. Also we know that the guy who gave it to him is Mister Monday and that Mister Monday is trying to avoid a punishment by giving this device to Arthur. Other then all of this information I don't know anything else about what is going on or what is going to happen next. Basically I am confused!!!
