Author Dennis M. Powers has penned numerous books about adventurous maritime exploits from treasure hunting to salvaging ships, but it’s hard to argue that "Tales of the Seven Seas" does not top the list for dynamite sea and human interest stories. The subject, Captain John O’Brien, lived and sailed during the exciting period of the late 1860s to early 1930s as full-sail ships became steamers, as the last glorious days of exploration ended, when South Seas royalty still held power, and a lack of regulation allowed adventure to flourish on the high seas. Whether a fan of maritime stories, or one who likes high adventure, every reader will be engrossed by "Tales of the Seven Seas." Best of all, this gripping story is true, yet seemingly so fantastic that it is based on fiction. Powers is the first author to compile the full story of Captain O’Brien, and no author is more qualified or more skilled at telling a good seafaring tale. Once they set sail, readers will never forget crossing the seven seas with Captain Dynamite Johnny O’Brien.
