This is Divergent in modern times but the whole gang goes to high school. Four is the school's bad boy player that every girl loves. Him and Tris HATE each other. Will love over come them? (I'm not good at summaries but I promise it's better then it sounds)

For a long time, we kiss like that, and I forget that the others are there, forget that there's a war outside the train, forget that we no longer have a home or a position in an uncertain world... Tobias' perspective from before "Divergent" through my "Determinant" alternate 3rd book, with lots of original scenes.
