This book follows on from 'Two Worlds' which covered the period from Abel Tasman's visit to Cook's in 1772, and explores the time from Cook's second visit to the establishment of the first missionary settlement. It is in three parts: science and whakapapa; utu, law and commerce; and tapu and religion. It is illustrated with black and white images and maps, and includes an appendix detailing the many visits by European ships during the period.
