This book could not have been written without the help of Dr. James Heath, professor of chemistry, University of California, Los Angeles, and Carolyn Chriss, researcher extraordinaire. This story is fiction. However, the science contained within it is real. The race to build the first molecular computer is real. Any errors or unintended exaggerations within the story are solely the responsibility of the author.
For their help and advice the author is also indebted to Terrill Lee Lankford, Larry Bernard, Jane Davis, Robert Connelly, Paul Connelly, John Houghton, Mary Lavelle, Linda Connelly, Philip Spitzer and Joel Gotler.
Many thanks also go to Michael Pietsch and Jane Wood for going beyond the call of duty as editors with this manuscript, and as well to Stephen Lamont for the excellent copyediting.
