Coalescent

Noodling around on Amazon, I stumble upon the paperback of Lydia Millet's Oh Pure and Radiant Heart. It does not say "nominated for the Arthur C. Clarke Award" on the cover; instead, the uncredited "synopsis" concludes:

"Oh Pure and Radiant Heart" is no more a SF novel than "The Time-Traveller's Wife". Instead, it is a powerful and original fiction of responsibility and guilt, today's America, and the peculiar terrors of our nuclear world.

However, customers who bought this item also bought Gradisil, Nova Swing, and Hav (and the paperback for the latter carries an Ursula le Guin blurb, which suggests they're not ignoring the sf market, at least). Ha.
