I also loved Kate Atkinson's Life After Life.
If people are like me and can take dark reading material--not so much graphic violence, but dealing with heavy subject matter--one book that comes to mind is We Need to Talk About Kevin, by Lionel Shriver. (I also admired her most recent novel, Big Brother. Kevin did have explicit violence in it, to warn you.)
Every Man Dies Alone, by Hans Fallada.
One of my all-time favorite novels, Jernigan by David Gates. Bleak and hilarious at once.
Mystery Ride by Robert Boswell.
I also recommend Middlesex. As well as A Visit From the Goon Squad.
Janet might also enjoy another of my top-ten favorites from way back in the Sixties. Absolute Beginners by Colin MacInnes.
I need to think up more! I haven't been reading enough fiction of late. This list is going to be a great help to me as well.
I also devoured The Secret History back in the day, so I'm happy that Donna Tartt is still writing engrossing novels.
