On a warm day in October of 1900, king Percival I dies at the palace in the capital. The state mourns his death. However, in the hours after the king's death, strange things happen. Adam Blackfort and Lucy Carston's parents vanish. Soon after, both Adam and Lucy are wanted for crimes against the state. Their history teacher, Mrs Wiggins, informs them of a coverup which happened long ago. Something that involved the king, the queen, Lucy's great grandfather, and Adam's uncle. The king, nor the queen, ever had any right to rule. Adam and Lucy flee their hometown Dunston to discover what happened in 1858, and why it could change everything today. With the king gone, his wife, the queen, steps up her game and announces she will take over. She defies the constitution which gives power to the Crown Council. Instead, she cements her position as rightful heir to the throne. And she begins her hunt for Adam and Lucy. Will Adam and Lucy figure out what happened, and prove it, before queen Claire is able to silence all opposition?
