The Opposite of Loneliness by Marina Keegan. A collection of wonderfully written short stories and essays by a young and promising writer.
The book is uneven and, at times, would have benefited from a bit more editing and revision. Tragically, however, that rewrite was impossible, because the author died in a car crash several days after her college graduation. This collection was published posthumously from the writing she did as a student at Yale and at the Buckingham, Browne, and Nichols School in Cambridge (where my younger son is now a student, which is how I first learned about the book).
