In the fourth part, Bella Swan faces a difficult choice — to save her own life or that of her child (half vampire, half human). She decides to keep the baby, but Edward and the rest of the Cullen family are категорически against it. Bella has no one to turn to for help, but it comes unexpectedly, from someone she least expected it from. Together, Bella and Rosalie try to save the baby’s life, not even realizing what horrifying consequences this will lead to.
