In a world in crisis, children are the future. Part of the cure. Not now. Children are deadly. Marked one to ten. Fiona is a TEN. She just doesn''t know it yet . . . She doesn''t know her true strength.

They have been branded as a warning to unvaccinated survivors. Key people needed to rebuild society are protected inside a fortress-like wall. Fiona has awakened branded, alone and on the wrong side of the wall . . .
