Notes from the Midnight Driver by Jordan Sonnenblick
16-year-old Alex decides to get even. His parents are separated, his father is dating his former third-grade teacher, and being 16 isn't easy, especially when it comes to girls. Instead of revenge though, Alex ends up in trouble with the law and is ordered to do community service at a senior center where he is assigned to Solomon Lewis, a difficult senior with a lot of gusto, advice for Alex, and a puzzling (yet colorful) Yiddish vocabulary. Eventually, the pair learn to deal with their past and each other in ways that are humorous, entertaining, and life-changing.
