She is sweet, kind, and always willing to help. Emma has a twin brother who she hasn't seen since her parents' divorce. She misses him a lot, but she knows that he hates her.

It's also home to seven boys with a secret: they may simply seem like players of the famous sport, Nightball, but they're actually vampires. To escape from their dark past, they try to lead normal lives as students - other than the occasional hitch since their rival Nightball team happens to be made up of werewolves. But in the end, these seven friends always find strength in each other. Until one day, a new transfer student with curious strength causes the boys' forgotten past to slowly unravel.
