Rafael Yglesias, A Happy Marriage
Joshua Ferris, The Unnamed
Both highly recommended. I'm still recovering from the latter, which I just finished this afternoon. They remind me of each other.
Both books are emotionally powerful (painful!) meditations on the nature of embodiment (as our bodies, by going badly awry, break through our preferred notion of ourselves as self-possessed) ... and how the realization that self-possession is a lie affects our deepest relationships.
I cried at the end of Yglesias' book. I just said "Oof" at the end of Ferris'. I think maybe that means I like Yglesias' just a tiny bit better. But I'll have to let Ferris' book sit with me a while to be sure.
