Jessica and Linda have been best friends since the first day of school. Both girls are from very different broken homes – and beautiful, wilful Jessica has always ensured their survival.

Now eighteen, the two girls have come to Wilde – an elite university in the heart of Dublin, far away from their troubled childhoods. Jessica thrives immediately, and, with the faithful Linda at her side, finds herself at the heart of a new circle of friends.

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.
