A couple of things should be said up-front, just because people have their own ways that should be respected, so if you don't like YA, this is YA. I used to be anti-YA, but then you get step daughters, and all of a sudden, YA ain't so bad. Also, a minor character is gay and it's a minor plot point. So if those things trigger you, don't read this.
The story is about two boys with opposing characteristics. Their lives are about as polar opposite as you can get, but there is something that despite their completely disparate lives, is shared. I will leave it there so as not to giveaway the MacGuffin, which comes somewhere near the end.
The story is a mystery thriller, slice-of-life. The story does not tie neatly into a bow, although there is a distinct plot twist that is kind of common to soap operas, but not common in real life. I love that. The writing is a little odd, to me. I don't love the writer's voice, but the story was told in an intriguing, entertaining way. This is an unexpectedly good, fun read.
