Kit Livingstone met his great grandfather Cosimo in a rainy alley in London where he discovered the reality of alternate realities.

Now he's on the run—and on a quest—trying to understand the impossible mission he inherited from Cosimo: to restore a map that charts the hidden dimensions of the multiverse. Survival depends on staying one step ahead of the savage Burley Men.

The key is the Skin Map—but where it leads and what it means, Kit has no idea. The pieces have been scattered throughout this universe and beyond.
