This is the fourth book in the adventure series by the writer, this is a science fiction too. After visiting Africa and Egypt, Dick and his four friends are now out to explore the mysteries of Bermuda Triangle.
One of the greatest books in my opinion ,though it is more like young adult fiction, but a young group of friends on an adventure is definitely my favorite genre, and no one could have done it better than Sir I.K Vijaliwala, i have read the whole adventure series thrice. Eagerly waiting for the next part.
