Twilight (novel series)
Bella also learns of Sam Uley the day she first rides the motorcycle. Sam Uley and his "cult," as Jacob describes them, are cliff diving (jumping off the cliff in la Push into the water below, for fun). Jacob is scared that Sam is doing something to control the young men on he reservation. When Jacob suddenly breaks off their friendship, Bella suspects that Sam has gotten to him. When Jacob sees how upset Bella is over their broken friendship, he makes her guess that he is a werewolf, because he cannot tell anyone that, and also that it is dangerous for him to be around her. He tells Bella that Sam is a werewolf, and his cult was actually a pack of the werewolves in La Push. He says that their purpose is to keep their reservation safe and they call them selves "protectors", and reveals that they were the wolves she had seen who had chased down Laurent. He tells her that they are still trying to kill Victoria.
