It’s a solid continuation of Jim’s story. When I first started listening to it I thought perhaps I missed a book as it referred to the mad mick. I even went back to the previous book and looked for mad mick’s part. Turns out the crossover is in the mad micks storyline in book Ultraviolent. Feeling like I missed something I got that book and listened to it first, feeling like I missed a part of the story. I don’t follow the mad mick series. It helped to listen to Ultraviolent first though if you’re not interested in that series and can overlook missing some details about a past event that is occasionally referenced I’d skip it.
