This book is supposedly a historical fiction story as seen through the eyes of a fictional character. Perhaps a unique approach but it does work. The story is well written with compelling characters.
However, the story is not really about Drake. It is an adventure story about his neophyte landlubber cook. The escapades of the cook stretch reality a bit but hover on the plausible.
There is no ending per se. Obviously this is part one of the Peregrine James series. Overall it is a decent and above average read. I particularly enjoyed the speech patterns and jargon of the period, If you like the pirate genre and do not need to read about historical figures as the principal character, you should enjoy this book.
