#1 -- "A Very Private Life" by Michael Frayn
Someone or something recommended Frayn's "Tin Men" to me some years back. I haven't picked that up yet, but I came across a used copy of this and gave it a shot.
And, uh... I guess it hasn't aged terribly well. Maybe in the 1960s it was groundbreaking but now the "all humans are distant from each other" thing has been done over and over. None of the characters are particularly compelling, and I really wasn't interested in the protagonist's fate. The social commentary is pretty dated and overall I just didn't get too into it.
It is, however, about 150 pages, making for a nice quick read on an insomniac night.
