Query: Disjointed

The first half of the novel is really interesting and a quick read. Then you get to the second half and it becomes disjointed and challenging to track exactly what is going on. This makes the novel frustrating as a whole. The ending is rather disappointing and anticlimactic, leaving much of the story unresolved, and the reader feeling like they just wasted their time.
