The greatest strength of this book is its fantastic and incredibly well written introduction, followed by great high-seas adventure full of pirate history and not Disney fantasy.
Historical stories of well known pirates such as Captain Henry Morgan, Captain Edward Teach, aka the infamous Black Beard, and the Isla de Tortuga are the most remarkable highlights and my personal favorites.
Even though I am a huge pirate fan, from watching every episode of Black Sails on Starz, to playing Assassin's Creed: Black Flag, and now have read a handful of pirate books... the genre as a whole is starting to get on the stale side for me.
I hate to say it, but seems like fiction or non-fiction it is pretty much the same thing, over and over again.
Things such as division in class with the wealthy and the poor, slavery, alcohol glamorization, "chasing after the girl"/sex/prostitution, lots of nicknames for captains and ships alike, the thrill of the hunt for wealth/treasure, venturing out into the sea and struggling through the challenges of the voyage, and finally lots of corruption, betrayal, murder, torture, execution, dueling, all of the rest of the darker sides of humanity... these concepts are just told in different ways, with pirates of different nicknames, chasing over different treasure (revenge, buried treasure of others, or a big "prize" aka a ship full of valuable cargo).
I just feel like this can only be spun so many ways... until you just find yourself back in the same "boat" and find yourself saying... haven't I already been here before?
With all that said, I would recommend this book to pirate fans, especially over fantasy based ones.
