As humanity teeters on the brink of extinction, a singularly unique girl named Melanie may hold the key to survival or become the instrument of ultimate destruction. In a desolate, post-apocalyptic world, where humans and the infected compete for dominion, Melanie's exceptional intelligence and heartfelt compassion challenge the belief that safety and cold science justify the sacrifice of the individual. Strapped into a wheelchair and closely guarded, Melanie's journey for knowledge, love, and the power of realizing one's potential will lead her to discoveries that could either redeem the remnants of society or hasten its downfall.
