My own fiction book list at present:
Red Star: the First Bolshevik Utopia by Alexander Bogdanov. I've been reading a pile of SF lately:
Kim Stanley Robinson,
Octavia E. Butler,
re-read Arundhati Roy's The God of Small Things,
and, since Fidel just died, to finally read from cover to cover his favorite book (For Whom the Bells Toll by E Hemingway).
I have a Wikipedia-created book on Collected Works of Bertoldt Brecht and am looking forward to it.
My non-fiction list is much, much longer.
