Description: This is the 41st book in the series, which is set in the year 2061. New York police lieutenant Eve Dallas investigates a torture-murder, the latest in a long line of torture-murders. This book is mostly a police procedural, with several interesting inventions not known to those of us here in 2016. Also, the reader knows who the murderers are, because chapter 1 begins in their POV.
Plot: Eve and her team investigate the torture-murder of a young man who plays in an orchestra. Along the way, they learn this is at least the 20th victim of two sadistic, psychopathic killers. The reader knows who these killers are, and it's interesting to learn how the police put all the clues together.
Characterization: Eve Dallas is the protagonist. Her husband Roarke and her partner Peabody are the main secondary characters. There are several other police characters, and a few side stories including one officer who is preparing to take the detective exam. Quite a few of the reviews I've read, indicate the character development isn't as good in this book as in the previous books, but I was able to get a feel for the individual personalities of each character, even though this is only the second book in the series I've read.
Overall: One note of caution: There is a LOT of torture in this book. In most places, it's not too gory, but from the dialogue and other information you're given, some of it seems over-the-top. Apparently, JD Robb [aka Nora Roberts] had some serious nightmares that she obviously needed to get out of her head and onto the page. Don't read this book if you don't like reading that sort of violence. It was almost too heavy for me.
