Welcome to the site turtle.

I think your English is very good indeed.
Mau is someone who has grown up with unshakable beliefs - his island, his family and his gods have always been very much a part of who he is. Then all that is destroyed and he asks himself why his gods would do that.
He then discovers that even the gods he believed is were false and he has to get rid of his old beliefs and try to create a world that actually works for him personally - and for his new Nation that he is chief of.
Daphne likewise, has to abandon the prejudices that she's been brought up with and see the people she is with as human beings rather then the 'savages' her grandmother would have thought of them as. She learns that people are people where ever they live and whatever they believe in.
For both of them the book is a voyage of discovery - not just of the island, but of themselves as well. They learn who they really are and what they really believe.
I hope that helps.
