Maybe 2.75 stars. I can't even decide whether or not I liked it. It wasn't bad. It was a sort of psychological thriller, without the thrill. I didn't find it suspenseful, but since I dislike suspense, that was OK with me. But I guess the main reason you keep reading is the same as the primary motive of the protagonist, which is to get to the end and get some sort of "reveal." We never get one. I have no idea what happened, and neither does our poor hero, which is terribly unsatisfying.
