What does the island, The Great Skellig, represent in the novel, Haven?

The Great Skellig is symbolic of the natural world at large. When the companions arrive on the island, Artt is thrilled because it has not been inhabited by other humans. The island therefore is a representation of nature existing on its own, untouched and unmarred by human influence. The ways in which the characters relate to and interact with the island reveals their sensitivity to others. Therefore, the author suggests that the way one treats the natural world is an indication of how she treats other people.
