The trumpet-major

Is this the single definitive Karen Rose book? Nah. If you haven't read her work, I recommend starting at the start of a city. That's Quarter to Midnight here, or Say You're Sorry, or Closer than You Think, among others. (Warning that most of them have children victimized somewhere, though not directly depicted. The real world is dark and she doesn't shy away from that).

But even a less standout Karen Rose book is really well crafted, with believably broken characters who heal over the course of the book. She's a master of her craft, and my personal favorite author. Minus a little main character plot armor, every lengthy mystery is incredibly believable and full of characters it's hard not to like (or hate). As an avid reader of nonfiction psychology, all of her motivations of all of her characters hold up really well to me.

This book specifically is fine standalone, but Phin's history with his family as a result of his PTSD is something you see start in Alone in the Dark, and there's been a level of suspense seeing him as a side character in the New Orleans series, waiting for his turn. The resolution of his relationships are emotional and reasonably well done.
