who sent him the message. Second Earth The story begins when Mark and Courtney have realized that they have accidentally destroyed the flume to Eelong trying to help Bobby. Courtney therefore becomes severely depressed and stops coming to school. Eventually she decides to go to summer school for six weeks in order to recover, so that Mark is left to read Bobby's journals alone. Throughout the summer, Mark collects Bobby's journals and reads them, and begins to have conversations with Andy Mitchell, the former school bully. Mark soon realizes that Mitchell is an adept in mathematics and became a bully for having been a misfit. Gradually Mark and Mitchell become friends. At her summer school, Courtney meets a boy named Whitney Wilcox, whom she befriends and of whom she begins to entertain romantic thoughts. Before long, he invites her out for pizza. En route, she is struck down by a black car which seems to have been following her. From the car emerges Whitney, who is here revealed to be Saint Dane.
