The author now follows two major directions to sustain suspense. Mention them and explain how the author uses them to maintain suspense

The themes friendship, sacrifice, and intolerance support the suspense. The theme of friendship is strongly demonstrated in these chapters. Even after many years of being apart, Sophie remembers David and saves him from the brutality of the Fringes people. She is even willing to risk herself by going to save Rosalind and Petra for David's sake. Another embodiment of the theme of friendship is Michael deciding not to go with the Sealanders because he feels it is more important for him to remain together with Rachel, the only surviving telepath left in Waknuk.

The theme of othering/intolerance returns, but this time in presenting the Other as the non-telepathic people, and the telepathy as an evolutionary advantage that gives them the right to eliminate the people of a lesser advantage. Evolution as a theme for regrowth of human kind is the driving force behind the ideology of the Sealanders.
