This story is filled with important events, and different readers are going to place emphasis on certain events more than others. For me, the first significant event is David discovering that Sophie has six toes. It is his introduction to a real life "Deviant," and what's great about the interaction is that he doesn't see it as a big deal. He even agrees to keep it a secret. The secret is eventually discovered, and Sophie and her family escape to the Fringes. Another important event is David and his group discovering their telepathic ability. Eventually, their secret is discovered, and they are forced to run away from the Waknuk society. They are hunted, and a climactic part of the story is when the woman from Sealand rescues all of them by immobilizing every person that is in the pitched battle. This is a very important part of the novel because it is here that David and readers discover that the Sealand people think they are a genetically superior people/species to the Waknuk people. David is shocked to hear this, but he has really no other choice than to go with her.
