A very brief outline of a novel.
-----
Wealthy family have 14 year old daughter. Dad has very successful business, they live in nice, big house, girl attends private school etc.
They're also foster carers.
Their next placement is a 14 year old boy. Gone off the rails, had bad upbringing, heading towards the prison/young offenders route.
He moves in with wealthy family. After initial "class clash" the teens grow overly fond of each other and become inseperable. This leads to problems with boy teaches girl a more exciting part of life that she has since been sheltered from.
As his influence grows on her, hr behaviour declines and eventually she is excluded from her school. Her parents see this as the final blow and begin the make arrangements for boy to be taken back into emergency care. Upon getting wind of this, the teens run away together. After a few weeks on the street, they become involved in petty crime in order to survive which gets more and more serious as conditions worsen until finally they 'reach the point of no return' and go too far.

That is very brief and I've made it sound cliche on purpose so the gist of it is easier to grasp.
Would it make an interesting story?
