The Awakening and the Struggle (The Vampire Diaries #1 & 2) by L.J Smith

 A deadly love triangle.

Elena Gilbert is a high school golden girl, used to getting what she wants. And who she wants. But when the boy she’s set her sights on—the handsome and haunted Stefan—isn’t interested, she’s confused.

She could never know the real reason Stefan is struggling to resist her: Stefan is a vampire, and Elena’s in danger just by being around him. What’s more, Stefan’s dark, dangerous vampire brother Damon has just arrived in town.

And wherever Damon goes, trouble always follows.
