This, the third in the series, introduces us to more characters, one of whom we will see a lot more of in future books. However, just in case you haven’t read the previous two books, this one takes place upon Ed’s return from his second mission into the past. (See - Marine 1: Agent of Time & Marine 2: A very Unusual Roman)Ed, a senior US Marine Sergeant has been told by a US Navy doctor that his active days are over, as his knee replacement is just not up to the task of an active service Marine. Having been given special leave by his Commanding Officer, Ed is on way to meet up with an old Marine buddy who is running a charter boat out of Florida. The charter is of a British scientific expedition to a remote island upon which some natives have been discovered who have been out of contact with the rest of the world for at least two centuries. Believed to be the descendents of a wrecked slave ship, the scientists seek to identify from where they originated by studying their language.Ed never got there, as he was targeted and recruited into a mysterious Time Corps, dedicated to patrolling the streams of time and preventing illegal interference with the time line.He finds himself propelled into the past at the time of the Napoleonic wars, as a woman. No sooner does he return from that one when he sets off once more to the old days of the Roman Empire.However, after returning from his last successful assignment in the beginning of the second century AD, Ed is now allowed to carry on with his life and to actually take a well-earned vacation.It turns out that a vacation is not going to happen, as the natives have a single racial memory of the men with white skins – that of the slavers who stole their ancestors all those years ago. Combine that with the news that a hurricane is on its way to the island mean that Ed is about to have to deal with a lot more than he initially expected.However, Ed, and his new friends discover a lot more to the islanders’ history and culture than they anticipated. Some of which have the ability to change lives –is it for the better?You decide!
