The Swan twins arrive in Forks. Bella is gloomy and hides the secret of the supernatural; Sienna is sunny, naive and secretly in love with Jacob Black. After chasing Bella empty-handed, Jacob realises that he loves Sienna, but turns into a wolf and, for fear of hurting her, brutally repels her and disappears for two months. During this void, Sienna meets Stiles Stilinski (cynical, sarcastic and sly). Stiles shakes her with pain and a strong bond is born between the two. When Jacob returns, changed and jealous, a love triangle is unleashed: Jacob wants her but pushes her away to protect her, while Stiles confronts the wolf with an open face to defend Sienna, until Forks' secrets come to the surface.
