Writing good sci-fi is hard. Peter Clines' "The Fold" starts at about 4 stars and ends with a 3... and he's lucky not to get a 2. He's got a fun take on the classic sci-fi trope of top-secret government labs, but the ending is contrived and doesn't really feel like the rest of the story. I did like how Clines handled his main character's eidetic memory and I enjoyed the overall tone, but the ending... just garbage.
