The Coral Island
by R. M. Ballantyne
Fifteen-year-old Ralph, the mischievous young Peterkin, and the smart, brave Jack are on a shipwreck coral reef, with only a telescope and a broken pocket crane among them. At first, the island seems to be a paradise with an abundance of food and a wealth of natural wonders. But then a group of cannibals arrives, followed by a pirate ship... which one should it be? A sequel to Gorilla Hunters is also available.
