The Spectacular Now - Tim Tharp http://www.divabooknerd.com/2013/09/the-spectacular-now-by-tim-tharp.html
The Spectacular Now isn't a romantic comedy, it's dark, brooding and the story of Sutter, problem drinker, party boy and life changer. He uses alcohol as a crutch to dull the ache of his mother, who only cares about appearances, his sister and husband, the golden couple and his father. But Sutter isn't willing to change, he enjoys the flighty lifestyle, but sadly drags everyone down with him. This is his tale of finding himself and faced with the prospect of wanting to be a better person, verses sinking even further into his depressive state.

Be warned, most readers will feel frustrated by the ending. Another perfect example why I enforce my self imposed John Green hiatus. It also applies to The Spectacular Now.
