I had some trouble following the plot, in part because the chapters jumped back and forth over a decade. But overall, I enjoyed this book. IQ is not your average detective. Instead he's a super smart black kid who has lost his beloved older brother, basically a parent to him. Yes, the book is full of profanity, but that didn't bother me. The author, Joe Ide, is a Japanese American who grew up in South Central LA, thereby getting the street smarts necessary to write this book. I'm looking forward to reading the second installment.
