Leo the Leper and the Senseless World

In a society where people are sorted into castes based on which senses they don't have,16-year-old Leo is in the lowest tier for being nose-blind, taste-blind, and partially numb. What's worse than being called a leper? The nonstop sensism is wearing him down. While researching a plague that caused sense-loss for 95% of the world, he discovers a strange spot on a map where everyone is unaffected. He's convinced they're hiding something. With few supplies, his pal Sam and their off-and-on friend Hux join him on a thousand mile quest for a cure. Along the way, they must also avoid leper hunters, sneak through hostile elite cities, and sidestep the chaos of leper shantytowns. What could go wrong? Just about everything.
