In the late twenty-first century the western world bathes in privilege, while the desert fringes of Western Africa drown in poverty and disease. From the oceans rise the immortals, turritopsis nutricula, after four billion years of waiting. Physicist Jeph Wallace discovers particles which alleviate all illness and ageing. He rejuvenates thousands of Mali's poorest, but the particles are tainted. Those treated fall blind, then comatose. Storyteller Yaye loses her entire community to the disaster. Driven by grief, she pursues Jeph as he flees from his guilt. Their flight drags immortals and humans through the depths of memory, beyond the edge of the universe and into the light of revelation. Light is the first in the Senses series, and the debut novel from author Tony Pitman.
