Return: Something amazing is about to happen to Diama and Micel. It was weird enough to have Joseph, a person from 2,000 years in the future living in their house, but what will their lives be like when two more visitors from Joseph's time pop into existence to share their lives? And these two newcomers aren't just ordinary strangers either. Far from it. They happen to be the exact duplicates of Diama and Micel. As if that wasn't confusing enough, a local warlord is making threatening noises of invasion, something that may spell the end of Micel's beloved home. To prevent disaster, Diama, aided by her double, proposes a radical and risky solution - a solution which sends Micel into a terrified panic. But what other course of action can be taken? Something radical has to be undertaken to save everyone, and Diama's solution, bizarre as it seems, appears to be the only solution. Friend or Foe?: Diama and Micel embark on a supposedly restful sea cruise but, given their track record of adventures, it's not surprising that nothing goes to plan. They find themselves being chased by pirates, nearly swept overboard by storms and searching for a mythical and fabulous buried treasure, thanks to a map which may, or may not, be authentic. The clues on the map are puzzling and mysterious, leading Diama, Micel and the map's owner - a crusty old sea Captain called 'Mad Dog' - towards a series of deadly traps. Will they even survive to find anything? And what of the sailor, Stan Gulley, who was rescued from the middle of the ocean ? He certainly appears to have his eye on Micel, much to Diama's increasing annoyance, but is he a friend or a hidden enemy? Micel believes the latter, and following events prove her to be right, but not quite in the way she expects.
