The quest for answers—and ultimate survival—hinges on finding the cosmic link between the Skin Map, the Shadow Lamp, and the Spirit Well.

The search for the map of blue symbols began in a rainy alley in London but has since expanded through space and time and includes more seekers.

Kit, Mina, Gianni, Cass, Haven, and Giles have gathered in Mina’s 16th-century coffee house and are united in their determination to find a path back to the Spirit Well. Yet, with their shadow lamps destroyed and key pieces of the map still missing, the journey will be far more difficult than they imagine. And when one of their own disappears with Sir Henry’s cryptic Green Book, they no longer know who to trust.

At the same time, the Zetetic Society has uncovered a terrifying secret which, if proven, will rock the very foundations of Creation. The quest for answers is no longer limited to recovering an unknown treasure. The fate of the universe depends on unraveling the riddle of the Skin Map.
