Discuss the ending of the novel. To what extent is it realistic or unrealistic, happy or unhappy? Give evidence to support your point of view.

The novel ends with the exact imagery with which it began: with an aerial view of the beautiful city that we now know is Sealand/Zealand. David, despite his general lack of action and lack of planning, has at last been able to bring one of his sleep dreams to fruition. In a grand finale of many of the themes seen throughout the novel, together with his Friends David has arrived in the safe haven of Zealand, and is no longer isolated, but instead is pursuing regrowth and evolution. I would have liked the author to develop the irony that the Sealand people were not entirely different in their rejection of "lower" species.
