Jist of it is that main character was a bully at school to one girl inparticular.
She becomes an adult, has kids of her own, feels guilty about her bullying behaviour and searches for the girl she bullied on facebook. Finds her, realises she's led a pretty crap adult life and makes it her mission to help her achieve more.
Things go ok for a while but the whole thing brings back memories that the bullied girl had actually surpressed and whilst the main character focusses on helping her build some amazing life, the bullied girl is actually plotting revenge.
Very, Very early stages yet but I'm thinking it will involve adultery, theft, humiliation etc etc as well as a bit of light comedy?
Would you give it a go?
