After watching Earth die in a storm of nuclear fire, Colonel Jack Reynolds and the last remnants of humanity’s lunar crew prepared themselves for the end. They were the final witnesses of human civilization… or so they thought. But when Jack wakes up in a pristine, seamless white room, free of every scar and sign of age, he realizes something impossible has happened. He's alive—and he’s no longer on the Collins lunar base. He soon meets his mysterious savior: Luna, an ancient AI who has lived within the Moon for over 450 million years, created by a forgotten alien race to observe and protect Earth’s evolution. Now sentient, lonely, and struggling with newfound emotions, Luna has revived Jack for reasons of her own.
