The higher score

Maya, 21, starts her junior year at Columbia University studying astrophysics. She's always been at the top of her class, until a transfer student, Alexander also 21, shows up. Both of them have the exact same classes. They begin an academic rivalry, however, Alexander did not come only for the astrophysics program. He came here for her, specifically. Maya notices an immediate attraction to Alexander, something almost ethereal about him. Is he just a transfer student, or is he something immortal?
