This is a quintessential boys adventure story: Ralph goes to sea as a cabin boy, almost as soon as they ’round Cape Horn and enter the Pacific ocean a storm sinks their ship marooning him and his two friends on a coral island on which they have wonderful adventures before escaping the island.
This book is in fact a prototype of several story genera, Ballantyne was a prolific writer of stories for young people, publishing over 100 between 1847 and his death in 1894. The Coral Island is considered his most successful in that it has never been out of print since it was published in 1858. Surely that is some kind of record in print for almost 160 years! If you like books similar to Lord of the Flies then here is the list with summary.
