Hi everyone.
I have been searching for this one particular book for several day now, Please help!!

This is what I remember
The books main character is a girl
the setting is semi dystopian, peopleare graded on how compatible they are with others.
her father who was scientist was framed (perhaps) so that all of a sudden he was compatible with no one and got taken away.
The girl schemes and plans for years,gets a fake name (I think) and enrolls in a school where the (presidents?) son goes, gives the son some sort of virus so that he is non compatible and so she ca pretend to help him to get him to help her take down his father.

OOkay. So thats what I remember.
anyone??

Best regards
