Bob s the author of the historical fiction novel, "Voyages of Malolo".  

Approximately 1000 years ago, over 500 year before Christopher Columbus was born, ancient Polynesians had managed to explore and populate over 20,000 islands in the vast Pacific ocean. For reasons of famine, religion, overpopulation, war or just the overwhelming human desire for exploration, these passionate and resourceful people set out on perlious voyages in wooden canoes to find new homes and better lives.

 Looks a fasinating book and 'm looking forward to chatting to Bob about it.
