In the following review of The Nature of Time and Space, Barrow states that the book's debate format works well and the author's theories are clearly explained.

General relativity and quantum theory have always held a special fascination for physicists. They govern empires that appear superficially disjoint and rule their separate dominions with a precision unmatched by any other products of the human mind. The accuracy of Einstein's general theory of relativity, for example, is demonstrated by the spectacular observations of a pulsar engaged in a gravitational pas de deux with a dead star. Einstein's expectations are born out by observations—accurate to one part in 10 14. Almost as impressive is the accuracy of the quantum theory: agreeing with experiment at one part in 10 11.

The quantum world deviates strongly from those of Newton when things are...
