Eclipse, the third book of the Twilight Series, is very mysterious. Seattle has become dangerous because newborn vampires are hunting people. Edward thinks they are outnumbered. Surprisingly, the werewolves decide to help Edward's family fight off the newborns vampires.
Later, Bella finds out that Victoria, a vampire who wants to get revenge on Edward by killing Bella, is leading the newborns. When the battle comes, the Cullens and the werewolves win, the newborns are defeated, and Victoria is killed.
Eclipse is awesome because it has exciting, mysterious, scary, and romantic parts.
