I rate this as one of the best books I have ever read, and I'm not young, nor an infrequent reader. It affected me deeply and took me to places in myself that are rarely touched.
The surface appearance is of a novel about racism and the difficulties it creates for those of mixed race. Even here, where one might expect little that is new, I feel that fresh insights and perspectives were offered. But underneath that surface is an examination of the very roots and resonances of identity, the relationship of an individual or group with artistic experience and cultural heritage, and a deep examination of what America is (as distinct from what it pretends or sometimes aspires to be) and of the threads of racial, cultural and religious arrogance which continue to inhabit American thinking.
It is a demanding read and one which probably benefits from a few years of life experience. There is much allusion to classical music, which while it does not require knowledge does demand patience with one's lack of it and the same might be said of the occasional scientific references. It is long book, but in my view not remotely "saggy" as one reviewer describes it. Its richness derives in part from taking the time to examine many facets and present the story (although narrated by one voice) from several character's perspectives.
I am not black, but would think this is a "must-read" for anyone who is, and perhaps for anyone who is of any form of non-white or mixed heritage (whether racially or culturally). Though maybe I shouldn't have said that, because this is fundamentally about being human and finding or recognising one's identity, and about what identity might mean to others. So just a must-read for human beings then.
I should not close without mentioning that the writing itself is quite beautiful, filled with poetic crystallised expressions and that the understandings of music and science are woven in with illumination and meaning. I am astonished that Richard Powers is not more widely acclaimed and that I discovered this book only by accident. I will be reading more of him.
