The title refers to the marriage of Jamie and Cathy, two appealing, twenty-something New Yorkers who set out on their romantic journey full of hope, optimism and vigor.
But the heart of the book is the story of how this full-blown late Romantic grew up in semi-detached suburbia by the River Thames during the second world war, and set out from there in search of a rainbow that turned out to be made of celluloid.
