The Paper Menagerie by Ken Liu. I didn't actually finish the book--I had to give it back to the library--but it's a collection of short stories, and I read all but the last two or three. Genre wise, this book is all over the map, including historical fiction, cyberpunk, epic SF, and urban fantasy. Liu's prose is very cleanly written (though not truly spare like a Hemingway), and the stories are all very thought provoking.
