Jill's dad has died by violent means and her Mum seems to have shut down, leaving Jill to deal with the aftermath of such a tragedy. At the funeral, the only person who offers the kind of support she needs is a boy who up until that moment has been just another face in the classroom. How is it that Tristan knows just how to comfort her? And how is that she lets him? Their relationship develops against the backdrop of the reality that they are descendents of the original Dr Jekyll and Mr Hyde, and as they slowly uncover more of themselves to each other, so the surreal quality of their lives increases; and the danger.
