But then Mark enters the picture. A philosophy student a few years older than them, he has strange and compelling ideas about self-discovery.
When Linda and Mark start dating, Jessica is disturbed by the change in her friend - and how quickly she seems to have fallen under this abrasive, charismatic man's control.
It turns out that Mark's influence is not limited to Linda alone; and Jessica soon finds out that her whole group of friends are keeping secrets for him - culminating in a terrible tragedy that strikes at the end of their first year.
Years later, Jessica is still grappling with her guilt over what happened at Wilde. And when Mark resurfaces, she knows she owes it to herself - and Linda - to set the record straight once and for all.
