This is a continuation of the story started in Seven Ancient Wonders. Which is a rather strange thing considering, All the plot lines wrapped up rather nicely at the end of that book when the machine was used and the planet saved. So i couldn’t see where this book was going to go. Well the story follows that, the Japanese find a way to undo the effect the machine had and that the solar flare caused by an enormously large sunspot (plot from previous book) was just a precursor to an even deadlier dilemma. A rogue planet of dark matter entering our solar system
Since dark matter isn’t 100% understood or identified, it can serve as a feasible plot device however we once again get drawn into the world of an ancient advanced civilization that died out eons ago. The same civilization that built the great machine from the first book also built six shrines around the world, which also held machines and giant pits that reach to an unknown depth. This idea was rather hard to swallow.
Regardless we are once again led on a wild ride as we try and discover the locations of these 6 shrines and the titular sacred stones to power them. However this story only covers several of the stones the rest are left for the next book.
This series while requiring some suspension of both, belief and scientific knowledge. It is still quite a thrilling adventure story and am really starting to like these main characters. Quite possibly because the Protagonist Jack West Jr is Aussie
