the twilight saga.
Here's a description of the first book:
Bella finds Forks a bit repetitive and lacking in joy. Despite the obstacles presented by the vampiric nature of the Cullen family, Edward and Bella fall deeply in love. Their foremost problem is Bella's alluring scent, which "sings" (new moon) to Edward and makes it difficult for him to restrain himself from attacking. The seemingly blissful state of affairs is thrown into chaos when another vampire coven sweeps into Forks and James, a tracker, sets his sights on Bella. Edward, along with the rest of the Cullen family, rescues Bella before James kills her. In the chaos James bites Bella, which complicates matters further; the venom injected into a victim of a vampire attack starts the process of turning the victim into a vampire. Beneath the surface, tension remains as Bella wishes for Edward to turn her into a vampire while Edward refuses to do so. The reason for Edward's adamant decision not to turn Bella into a vampire is not revealed.
