Search - After Midnight (Youngbloods, Bk 1)

From the Amazon Product Description:
Sophomore Catlyn Youngblood is used to the nomadic existence she and her two older brothers have shared since the death of their parents. When they settle down for good in the sleepy backwoods town of Lost Lake, Florida, Cat thinks they might finally fit in. Instead, they're shunned by the locals.

While riding her horse late one night, Cat meets an enigmatic and handsome boy named Jesse Raven. Even more strange than her overpowering attraction to him is Jesse's apparent aversion to the sun. As their attraction intensifies, long-kept secrets come to light. Cat learns that the Ravens are a centuries-old vampire clan . . . and worse still, that she and her brothers are descendents of Abraham Van Helsing, the world-famous vampire hunter. Mortal enemies by blood, the two families do all they can to keep them apart. But Cat and Jesse will risk everything to be together—including death.
