I enjoyed the writing and the pacing was... Motivating, I guess. It kept me engaged. Several things did not age well here, though.

Gender essentialism with the uterus, Rizzoli's whole character is developed around her looks without a lot of depth/appreciation for the systems around her (although there's some acknowledgment of the pressures on her as a woman in the department, it feels really surface level), and the flaw in her character being she just wants to kill suspects - definitely not a good look and something she'd struggle to come back from, for me.

Also weird there's no Isles? I guess this is just further confirming for me that when it comes to books I like cozy detective stories/mysteries, not "modern day" police procedurals. But if that's your thing, the writing here at least could sell you on this. I can see why they wanted it for TV. (I listened to the version narrated by Laurel Lefkow).
