As the crow flies, the scar across Jillian Campbell's face runs from the top left of her forehead to the bottom right at her jaw. The scar's true path wriggles and jags, taking a detour around her nose. She has teeth only on the top left half of her mouth and the bottom right. Her jaw is locked. She is legally blind. A plaster on her brow covers a hole that has not healed in four years. An X-ray would reveal 164 titanium screws in her head.
