The Coral Island [SEP] Plot summary
The story is written as a first person narrative from the perspective of 15-year-old Ralph Rover, one of three boys shipwrecked on the coral reef of a large but uninhabited Polynesian island. Ralph tells the story retrospectively, looking back on his boyhood adventure: "I was a boy when I went through the wonderful adventures herein set down. With the memory of my boyish feelings strong upon me, I present my book especially to boys, in the earnest hope that they may derive valuable information, much pleasure, great profit, and unbounded amusement from its pages." The account starts briskly; only four pages are devoted to Ralph's early life and a further fourteen to his voyage to the Pacific Ocean on board the "Arrow".
