One year on from the day the shadows shifted - showing people their truest selves rather than just their shapes - best friends Teddy, Betsy and Effie plan to risk all and watch the winter sun rise over Copperwell, in defiance of the Shadow Order. But from their hidden vantage point the three shocked friends witness a mysterious woman shouting a dire warning, before she is arrested, beaten, and dragged away in handcuffs. The event leads them on an extraordinary series of dangerous adventures to save their city as they begin to learn the truth about the Shadow Order, the world surrounding Copperwell, and themselves.
