New moon Novel by Stephenie Meyer (The Twilight Saga, #2)

For Bella Swan, there is one thing more important than life itself: Edward Cullen. But being in love with a vampire is even more dangerous than Bella could ever have imagined. Edward has already rescued Bella from the clutches of one evil vampire, but now, as their daring relationship threatens all that is near and dear to them, they realize their troubles may be just beginning.
Bella and Edward face a devastating separation, the mysterious appearance of dangerous wolves roaming the forest in Forks, a terrifying threat of revenge from a female vampire and a deliciously sinister encounter with Italy’s reigning royal family of vampires, the Volturi.
