Omparison of The Poisonwood Bible and The Heart of Darkness

I didnt write this on time and I am already expecting a low grade. I really need help on this one to even out the blow its going to give me in English. I am really good with my academics, and have a thirty-five on the English part of my ACT, but Ive all but checked out this close to the end of school. The essay is simply a comparison of two works we have read in class. It would probably be best to have a comparison the essay could center around, but I also wouldnt mind multiple comparisons. Thankyou, you have a returning customer already.
