Jack has been wondering about the disappearance of his father for over a year now. Tucked away in the remote village of Rothchild, all the children have been living on their wits since their parents were carted away by order of the Queen. When a passing stranger entrusts him with stabling his horse for the night, Jack takes the opportunity to ride as fast and far as he can out of town and toward London. His plan is to find his father, but with no money and little knowledge of the world, he finds danger and adventure instead. It doesn't help that the closer he comes to finding his father, the closer he comes to uncovering a ruthless plot to overthrow the monarchy. What begins as a simple journey quickly turns into a swashbuckling adventure of epic proportions as Jack is joined by none other than Prince Albert himself. With the help of the Prince's royal bodyguards and Jack's own scrappy courage, they just might be able to uncover the truth of the plot against the throne, Jack's missing father, and the mysterious Doomsday Device that threatens them all.
