Breaking Dawn
The book is told from Jacob's perspective.  He receives news of Edward and Bella's return, and that Carlisle has told Charlie that Bella is quarantined because she has contracted a rare disease in South America. Jacob assumes that Bella has been bitten and transformed. He is upset when Sam Uley, acting Alpha of the pack, declares that the pack will not retaliate. Jacob, full of anger, decides that if the pack will not retaliate collectively, he will act alone. Formulating strategies of attack, he runs to the Cullen house. When he arrives, however, he discovers that things aren't as he expected. Bella, as opposed to being a newborn vampire, is already heavily pregnant with Edward's and her child. It is clear that the child's rapid growth is starving and hurting Bella.
