In a world where the lines between human and vampire are sharply drawn, Elena, an intelligent yet unpopular teenager, finds herself drawn to the mysterious and captivating Jason. A 900-year-old vampire who appears to be no older than 18, Jason has always lived in the shadows, obeying the strict rules of his ancient vampire father, Victor. But Jason’s half-human blood makes him immune to sunlight, and for the first time in his long life, he longs to remain in the human world—despite his father's disapproval.
