Serena Campbell, still getting over her mother's death, moves to Watertown, New York, with a population less than 3,000. The same week, a hot jock named Alex Bentfield does the same. Things don't start out on a good note for them, but when they get paired up as partners for the Heredity Project in their Life Science class, they learn that they have one key thing in common: Serena's mother's death.
