Reborn: Shadow Falls: After Dark, Book 1 (paperback) C.C. Hunter
Della had the perfect life-the family, a boyfriend, and a bright future-until she was turned, and abandoned by everyone she loves. She takes refuge at Shadow Falls, a camp for teens with paranormal powers. It's where she and her best friends, Kylie and Miranda, heal their heartbreak with laughter, and where Della is training to be a paranormal investigator-and she refuses to be distracted. That means there's no time for romance with Steve, a gorgeous shapeshifter whose kisses melt her heart.
When a new vampire named Chase shows up at camp, Della's world is thrown into even more chaos. Arrogant and annoyingly sexy, Chase is a mystery . . . and the only mystery Della likes is one she can solve. She can't solve Chase, at least not while she's dealing with ghostly hauntings, vampire gangs and a web of family secrets. Can she prove herself as an investigator and keep her life-and her heart-intact?
