This is the 7th in Cook's Garrett series ("Sweet Silver Blues," "Bitter Gold Hearts," "Cold Copper Tears," "Old Tin Sorrows," "Dread Brass Shadows," "Red Iron Nights," "Deadly Quicksilver Lies," "Petty Pewter Gods," "Faded Steel Heat," "Angry Lead Skies," and "Whispering Nickel Idols"). Unfortunately, it's not up to par with the rest of the series. First, the book just seems to wander around in the middle. Garrett doesn't seem to be going anywhere with the mystery. It does pick up near the end, but that leads to the second problem: the solution to what's been happening just doesn't mean anything. We know who did what to whom and why (mostly). But, nobody really gets anything out of it. For the reader, the answers to all the questions are just emotionally empty. The final "big" problem with the book is that the character of Garrett's love interest, "Chastity," just falls apart. She's fine through most of the book, but then at the very end, she just drops out of the character (personally, emotionally, and professionaly) Cook set up for her. There's no explanation for it. It's very jarring and unwelcome.
Because of this, I can only rate this book at an OK 3 stars out of 5.
BTW: At the time of this review, this book is long out of print. It's tough to find anywhere. As an alternative, look around for the SFBC's "Garrett Investigates." This book is part of that collection.
