Query: Impenetrable and boring

Probably the first problem is that I'm not a musician. And while I like jazz, I'm not consumed by it. It seems being a jazz musician is a requisite for enjoying this book. I wanted to read a book that propelled itself on plot, on character development and on some sort of emotional connection. Instead, I found a book whose writing mimics a jazz riff -- technically dazzling but self-absorbed and cold. I couldn't get through it.
