Fancy this: You're rushing through the London rain-late to your appointment, getting soaked and cursing your luck-when suddenly you find yourself in a wholly unfamiliar place chatting with a crazy old man by the name of Cosimo. He not only knows everything about you but claims to be your great-grandfather. And then, before you know it, you are hurled into the midst of an unlikely adventure involving the hidden dimensions of the universe.
That's precisely the situation Kit Livingstone finds himself in. He doesn't understand it, but it involves alternate realities and is somehow related to ley lines, or force fields of telluric energy...and the groundbreaking experiments of the bizarrely tattooed traveler Arthur Flinders-Petrie, a.k.a The Man Who Is Map.
While Arthur Flinders-Petrie is long gone from this plane of existence, he left a part of himself behind...a Skin Map. It has since been separated into five pieces-but as the old man Cosimo explains to Kit, the reassembled map might just lead them to "the secret of the universe-or something even more significant and momentous."
Problem is, there are numerous unsavory forces on the same quest-willing to do whatever it takes to bend time their way and eliminate anyone standing between them and the map pieces leading to the universe's ultimate prize.
