Computers have failed, electricity is extinct, and the race to discover new lands is underway! Brilliant explorer Alexander West has just died under mysterious circumstances, but not before smuggling half of a strange map to his intrepid children—Kit the brain, M.K. the tinkerer, and Zander the brave. Why are so many government agents trying to steal the half-map? (And where is the other half?) It’s up to Alexander’s children—the Expeditioners—to get to the bottom of these questions, and fast.

Kit, Zander, and M. K. West are settling into their new lives as students at the Academy for the Exploratory Sciences when Kit finds another mysterious map left for him by their father, the brilliant, famous — and presumed dead — explorer Alexander West. Why did Alexander leave the maps behind, and why are government agents so determined to seize them? What is really going on in a mysterious and unknown stretch of the Caribbean, famous for its violent storms and shipwrecks? And what is the huge contraption M. K. is building in her workshop? As two world powers come to the brink of war, Kit must find a deadly hidden island and unlock its secrets, hoping he has the courage to follow the trail of maps, wherever it may lead.

In a world in which the computers have crashed and it's discovered that the maps of the world are all wrong, the children of a famous explorer must follow a series of maps left their father.
