It was a decent read.
Do I regret reading it? No
Did it blow me away? No
The main thing that bothered me is it took over halfway into the book for anything to really happen, and the ending felt extremely rushed. What's the point of building all that suspense, and then falling flat with the ending.
It was basically "This person got murdered, this person got arrested, and then everyone went home. The End."...
The ending would have been more satisfying if the author had written another 15 pages or so to properly wrap things up.
