In the months that follow, Bella learns that thrill-seeking activities, such as motorcycle riding, allow her to "hear" Edward's voice in her head. She also seeks comfort in her deepening friendship with Jacob Black, a cheerful companion who eases her pain over losing Edward. Bella later discovers that Jacob is a werewolf. He and his fellow werewolves protect Bella from the vampires Laurent and Victoria, the latter of whom seeks revenge for her dead mate, James, whom the Cullens killed in Twilight.
