A vibrant living world connects to the Shift World, a world of monsters, ruins, and treasure. One in ten thousand people can travel between the two worlds and they are known as shifters. Shifters created empires, became merchant barons, and influenced much of the world's culture. Schools teach about shifters' exploits and shifters even dictate fashion and entertainment. Children dream about a life of adventure in the Shift World.
A young shifter named Karp was saved from the brink of death in a small trading post called the Village of the Traitor's Tavern. While recovering she befriended the general store's manager and apprenticed under a local shifter named The Whitecoat. The store manager, her adopted son, and The Whitecoat became Karp's family and the Village of the Traitor's Tavern became her home.
Karp's idyllic life is threatened by a spreading sickness which takes the lives of shifters. An encounter with a mysterious stranger in the Shift World almost leaves Karp dead on the general store's floor. To save her new home and family, Karp will need to search the ruins of Shift World for weapons, find powerful new allies, defeat unrelenting enemies, and avert an unclear calamity that looms over everything.
