No One is Talking About This, by Patricia Lockwood
First half is a horrifyingly accurate and funny depiction of the extremely online life and what it does to your attention and sense of humor and so forth. Second half is basically about the online brain being confronted with a family tragedy of sorts that is very real and not funny and a constant physical presence. I found it very effective and moving.
The Road Back to Paris, by A.J. Liebling
Great stuff, WWII writing published while the war was still on. Liebling was a war correspondent by necessity, but he mostly wants to write about good stories he's heard and recount interesting conversations. He's a very relaxing writer to read, even when he's writing about the darkest days of the war. This was in a collection of his WWII writing, the next volume has the "Mollie" story, which is a fantastic account of a dead soldier that seemingly everyone had heard of, and investigating the legends surrounding him and eventually finding the people who knew him back home.
Utopia Avenue, by David Mitchell
The first book of Mitchell's that has actively annoyed me, about a legendary British band from the late 60s that seems to combine Fairport Convention and the Pretty Things and a few other bands he thinks are cool. He throws in a million 60s celebrity cameos and they all have some vaguely profound things to say, it all comes off like fan fiction about the 60s and the only interesting strand of the plot ends with the same deus ex machina resolution as his last couple books.
The Catcher in the Rye - had never read this, I think it's pretty alright. Probably would have annoyed me more if I had read it 20 years ago but it worked well for me at age 35.
