If you're an adult looking for a thriller that will actually make you feel something (even if that something is a bit of nausea), the Will Trent books are top-tier. Karin Slaughter is a pro, and these books are way grittier and more complex than the TV adaptation.
However, from a parent's perspective, these are 'top shelf' books. They deal with the kind of visceral, psychological horror that stays with you. It's great literature for the genre, but keep it far away from the kids' nightstands. This isn't a 'fun' mystery; it's a deep dive into the architecture of trauma.
