Dawn Maddox has a secret that could rewrite human history. To the students at her new high school, she’s just the quiet girl with a talent for Shakespeare and a mysterious past. They don’t know that she used to be Daniel Shurin—a forty-year-old scientist who traded his life for a teenage body to escape a grief that was consuming him. Living as Dawn is a performance more demanding than any role on stage. She has to learn the unwritten rules of girlhood, the weight of new friendships, and the terrifying, fizzy thrill of a first crush—all while carrying the memories of a man who lived for forty years without ever truly living. But as the "Lola" procedure becomes a global flashpoint, Dawn’s double life begins to fracture. The science she created is being used as a weapon, and the "David Byrne" pseudonym she used to protect herself is now a target. In a world obsessed with the "Grass is Greener" promise of a second chance, Dawn is finding out that the hardest part of being sixteen isn't the science—it's the soul. In the end, the only thing more dangerous than the truth is the cost of keeping it hidden.
