Your GPA, SATs, and course load are all strong points in your applicant, and undoubtedly they will help your application. Most of your ECs are typical, but publishing a novel is a pretty impressive accomplishment. The only thing holding you back, in my opinion, is your lack of major awards (AP scholar and National Merit don’t really count.) Assuming your essays and letters of recommendation are good, if you apply ED I’d say you probably have a 50y/50n chance. That’s pretty much as good as it gets for any top school.
Best of luck!
