The Cay by Theodore Taylor

A boy and his mother flee the Carribean at the start of World War II, but their boat is hit by German submarines. Phillip ends up injured and afloat with an elderly black man - the start of their survival adventure.

This 1969 children's book was recommended to me by a former librarian who cited it as a forgotten favorite. I read online it has been criticized as racist - and while there are spots of racism, they're included to show how Phillip grows and learns. How the experience allows him to overcome perceived differences and learn what even his mother didn't know.

The book moves quickly - despite the fact it covers quite a bit of time, it's only 140 pages. To keep kids interested and engaged it's dramatic but doesn't dwell overlong on the machinations of life marooned on the island. I found it interesting and well told.
