I read Nicholas Christopher's Veronica several years ago, and I remember it being dizzying and dazzling—and ultimately a bit unfulfilling. And so with this one. It was engaging, with two interwoven plotlines moving toward each other, and it did have interesting characters, dialogue, etc., but ultimately it was kind of unsatisfying.
Here's a quick synopsis that isn't spoilery: The first plot is in the past—it's the sort of untold history of the man who influenced all modern jazz, I guess. I have no idea if that guy is real or not; certainly there are a lot of real people discussed in his story, but I was too lazy to Wikipedia it. The second story is modern: a woman whose husband just left her for his secretary, and whose mother just passed away, goes on a semi-manic road trip with her daughter to deliver a talk at an anesthesiologist conference.
I had two main problems with the book. First, it's incredibly difficult to write convincingly or satisfyingly about music. No matter how eloquently you describe a song I've never heard, chances aren't good I'll be able to hear it in my head, or even have a clue what it vaguely sounds like. And second, the jazz plot dra-a-a-a-a-agged. I'm not a dutiful student of history, and it's clear that Christopher really nerds out on this stuff, but the barrage of names and places and very short descriptions of each just never sunk into my brain, so that when this or that person or club recurred, many chapters later, I was lost as to its significance. I think he just tried to cram in more than the book could bear—or at least more than I could bear. If you're more of a lover of music history than I, perhaps you'd think differently.
Anyway, at the very end the book really redeemed itself for me, tying everything up quite well, in an unpredictably and not at all corny way. So that was great.
I wish it came with a CD (or MP3 download key or something) of the music, though.
