Almost forgot to post my own list. In no particular order:
Last Night by James Salter. Short stories like a knife in your soul.
The God Delusion (science/religion) by Richard Dawkins. See Floodlights.
The Lost Painting (art/journalism) by Jonathan Harr. See Current Obsessions: Caravaggio.
American Purgatorio (novel) and I Am Not Jackson Pollock (stories) by John Haskell.
Suite Francaise (unfinished novel) by Irene Nemirovsky. Manuscript stashed in a suitcase, a devastating memoir of Paris in WWII.
