Oh man this was one very intense! I think this was less mystery and more thriller, which is a cool kind of genre change up here. It also meant I personally was so much more tense and screaming at the book at certain points. But if you want Criminal Minds for kids, this is right up your alley I think. (The cop/carcerality stuff uh bugged me but ymmv, most kids books are not written for prison abolitionists.)
