Your sister "taking the blame" will be committing insurance fraud, and she will be making false statements to insurance and police officers. What you need to do is call the police to file a report (the fact that you haven't already is leaving the scene of an accident - another law you've broken). If you had done that, then all that would have happened is insurance would have settled everything out.
So now, you need to act like a damn adult, call your recruiter, and delay shipping until you fix this. Have some damn integrity.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
