DAVID'S CHILDHOOD IS MISSING When David Glass was fifteen, ERIN struck nearly a million people worldwide. The virus gradually destroyed all memories formed before infection. Eight journals written when he was diagnosed are all the orphaned David has of his youth. They shaped him as he started a new life. Twenty years later, he has turned the side effects of his memory loss into a career in perceptual engineering. He built a loving family but still has a burning need to remember the idyllic childhood his younger self wrote about. When a treatment is developed that can restore his memories, he leaps at the chance. He doesn't know his journals are fiction. He doesn't know his younger self was a psychopath.
