'The Mummy's Revenge'

This RP is based on the book, "The Mummy's Revenge" by Roy Pond. It is about this boy and his cousins playing an Egyptian Mummy Monster game and slowly being stuck inside the game and fighting for their lives. In the game, you are to find the pieces of Osirus (sp?) before he is to be judged by Anubis. However, Osirius (??) has an evil brother who has stolen his body parts and hidden them in this tomb like thing, guarded by 'mummy monsters' and puzzles. We will follow the book as closely as possible, therefore I need someone to play as Amy and Josh (the cousins that are bro and sis) while I am playing as Harry (the boy). Harry is staying with Amy and Josh(Josh is older, but the same age as Harry) while his mother, an Egyptologist is out on the job. If you have any questions please feel free to PM me.
