Hunter's Run, written by Gardner Dozois, George R. R. Martin, and Daniel Abraham is a hardcore science fiction novel. I enjoy science fiction to an extent, Ender's Game is still one of my favorite novels, but this was an extreme alien immersion. And I actually enjoyed it.
The language in the novel was strong, but perfect for the character of Ramon, the rough, dregs of society that he was.
I give the book 4 of 5 stars.
