The first major event of the story is Felix running away form the orphanage to find his parents. This was important because without Felix running away, nothing else would have happened in the book. The next major event was Felix finding Zelda. Felix had been alone on the hunt to find his parents, but he soon found Zelda and kept her like his younger sister. The major event after that would be Felix and Barney going to the city and Barney taking them to his house. That was important because without Barney, they would have been sent to death camps or could have died. After that, Felix and the other kids at Barney's house get caught and are taken on a train which was supposed to go to a death camp. On the train, Felix finds a hole in the train and Felix, Zelda, and Chaya (a girl at Barneys house) jump through it. Chaya dies but Felix and Zelda live.
