Hi, Iconian,I think you've made a lot of progress on this query since I first read it!
Best friends Jynnete and Katy have just started their second semester at their California college―but after a racially-motivated shooting occurs on campus, their worlds begin drifting apart. The BFF's have always been something of an odd couple: Katy is a compassionate and free-spirited fashionista, while Jynnete is a strong-willed Christian feminist studying chemistry.
But ('But' seems like an unnecessary word--maybe start with "in the wake of the shooting") in the wake of the shooting, with the community turned upside down and students turning out in droves to attend the college's “End Prejudice Campaign,” their differences might just be too great to overcome. Katy's native sensitivity draws her to volunteer for End Prejudice, and pushes her into the arms of the worst possible choice for a new boyfriend―at least in Jynnete's eyes. (I think this could still be condensed. Something like: BFF's Katy and Jynette have always been an odd couple: Katy is a compassionate and free-spirited fashionista, while Jynette is a strong-willed Christian feminist studying chemistry. Katy and Jynette have just started their second semester at a California college when a racially motivated shooting occurs on campus. In the wake of the shooting, Jynette and Katy's friendship is strained as they find themselves pulled in different directions. Katy's sensitivity draws her to volunteer for an End Prejudice Campaign and pushes her into the arms of the worst possible choice for a new boyfriend--at least in Jynette's eyes.)
I assume one friend is white and one African-American? If so, I would mention that.
Soon Katy's friends try to get her to break up with her baffling (maybe cut this word) new beau, fearing he'll use and corrupt her, but she clings to him even more strongly. (Why doesn't Jynette like the new boyfriend?) For one of the first times in her life Jynnete begins to feel powerless, forced to watch her friend move in almost every perilous direction that she had tried to help her avoid. (Maybe reduce this sentence--Jynette feels powerless as she is forced to watch her friend ignore her advice.) And even as Katy contemplates marriage, Jynnete struggles even harder to break her free, but does little except increase tensions and garner herself accusations of prejudice. ('When Katy goes so far as to contemplate marriage, Jynette confronts her friend, and in an angry showdown Katy accuses Jynette of prejudice toward her boyfriend.' This isn't the best phrasing ever--but I hope it will give an idea of what I meant by condense.)
With their second semester of college drawing to a close, boycotts, a mayoral recall and riots threaten the whole city. Katy's future already seems decided, set on a path of bleakness and denial. Jynnete's interventions and exhortations all seem to be backfiring, and she now watches almost helplessly, wondering how she's distanced herself from her friends, her own new boyfriend, and even her beliefs. And at any moment everything might totally change or collapse, with untold stories sending everyone careening down still more uncertain paths. (Again, I would probably try to condense this paragraph and streamline your ideas.)
I think this query has improved a lot, and you are well on your way!
