An entertaining and interesting overview of some of the issues surrounding the interpretation of quantum mechanics. The author has a strong opinion that the Copenhagen interpretation (to the extent that such a thing exists) involving wavefunction collapse is bankrupt, although he's not certain which of the competing interpretations are correct.

The book lingers more on the story of the people behind the science and how various interpretations were formulated and debated than on the technical or philosophical issues associated with each interpretation, although these are also briefly discussed.

Overall I think that this is a great book for a layman (such as myself) who wants a brisk, readable introduction to some of the history and controversy surrounding the science. I also think that the book is interesting enough that readers might be inspired to explore the subject more deeply than this book allows after reading it.
