The book is originally written in Hebrew I think and the prince is ten when his parents died and he became king. At some point he gets exiled for doing a bad job and there is also a specific scene i remember where his plane crash on a remote island that inhabits cannibals and while the prince survived the pilot died in the crash. In addition he doesn't get eaten by the cannibals because of a prophecy about a metal bird that would fall from the sky as a sign for the cannibals to stop eating people.
Roughly when (what year / decade) did you read it? Which language did you read it in? Was it a book for children, teens or adults? Fiction or a true story?
It sounds crazy but I swear this book exists 😅
