It’s YA (characters are college kids), but doesn’t withhold the sex, drinking and fighting (kind of Fight Club-ish). The characters propelled me through their ballad of love and hate, and the plot was all over the place surprising and dramatic. And, whew! that boy. Warring between wanting to kiss him and castrate him, I went through the full range of emotions from shocked to sick to my stomach upset to grinning like a fool. Few books that can do this on a satisfying level.
