Found on a list of detective-type books that are not by white authors and mainly don’t have white characters. This is about IQ (his initials, real name Isaiah Quintabe) who is a scary-smart young man in a rough neighborhood with a keen problem-solving mind. He gets sought out by people, some of whom pay him and some of whom don’t, or only pay in muffins. I really liked the main character and some of the supporting ones, the book was a little too violent for me and has some roughed up dogs. You get a lot of insight into his backstory in this one. I might read one more to see how they are.
