Foe

I enjoyed this. While I did guess one of the twists right away, I second guessed it many times and there were plenty of red herrings that led in various directions so it stayed interesting. It did feel like it could have been a novella or short story and worked just as well.

In the end it really felt like a parable about relationships.

I think where it felt less successful was in some of the more science-fiction-y ideas that it was trying to explore. Due to the nature of the way the story unfolded, and the twisty ending, you can't really appreciate some of the big questions the book asks until the end, and by that point the details that would make those questions most interesting are less fresh in your mind. There's also just a lack of depth to a lot of the descriptions, and some real plot holes which did slightly take away from the story. But overall I did enjoy it a lot and it kept me reading.
