Just finished Chester Himes' A Rage in Harlem, it's the second of his novels I've read and they've both been compelling reading.
Finished the book, hated every page of part 4. I really can't understand why he'd do that, other than drug addiction or going cold turkey.
It was definitely a tonal shift. Given all the delays in it being released, I can only imagine the editing process being even worse that usual
Just finished Dostoyevsky's Notes from Underground, which got a bit heavy going in the middle but suddenly became a ripping great yarn. I'm now on Vonnegut's Slaughterhouse Five, which is going well so far but I've only just started.
