Query: Disappointing Effort

This book promises a great deal but unfortunately, fails to deliver. The subject, Britain's Royal Navy and its impact upon history and the world we know today, offers an extraordinary range of possibilities for any writer. In this case, beginning with a strong intriguing premise, the book fails to deliver on a number of levels. Most significantly, the number of historic errors totally erodes the reader's confidence in the writer's general proposition. There are just too many mistakes and for me at least, the scholarship of the entire book is called into question. Despite the Royal Navies full, rich history and the exciting possibilities of the writers premise, sadly, I found this book to be very disappointing and I would not recommend it to others.
