Teenagers Peter, Benny and Jason secretly prepare for the adventure of their lives - a journey to the heart of Mystery Mountain. But soon they are trapped in a place that's viewed with deep trepidation by the people of the remote West Indian village from which the youngsters come. Are the villagers' fears justified? Is there really something sinister about the mountain? And is there something supernatural about the thunder and lightning which habitually lash it? Or have the lads stumbled on something altogether more wholesome - a splendid hidden world with exotic wildlife, lush vegetation and breathtaking scenery? We don't have to wait too long to find out. But the mountain yields its deepest secrets as grudgingly as it releases its prisoners. Secrets like: Where did the mysterious talking bird Eden come from? And is there another way out of the mountain? The author sustains a cracking pace and knows exactly how to keep her readers in suspense. And she still finds time to give us some useful snippets of information about West Indian history and true glimpses of West Indian customs and village life in the 1950s.
