Showing After Midnight by Lynn Viehl

Ever since the death of their parents, Catlyn Youngblood and her two older brothers have shared a nomadic existence, always moving from place to place. When they at last settle for good in the sleepy backwoods town of Lost Lake, Florida, Cat thinks she might finally have a normal life.

While riding her horse late one night, Cat meets an enigmatic boy named Jesse Raven. Even more strange than her overpowering attraction to him is Jesse's apparent aversion to daylight. Only under the cover of darkness can they meet. As Cat and Jesse's bond grows stronger, Cat discovers an incredible secret about the Ravens' and her own family's pasts—a secret that could destroy their love. Their families, knowing the truth, conspire to keep them apart. But Cat and Jesse will risk everything to be together . . . including death.
