After John Lancaster's failed takeover of England, the Knight of Colchester now looks to restore the realm's rightful heir. The child king's whereabouts have been unknown for some time and some even assumed him to be dead. However, knowledge of Henry VI's location is soon learned, and so Sir William and his allies set out to find and bring the future king back to London. During this undertaking, it is discovered John Lancaster had many more friends who supported his cause. An army of Lancastrians, led by another uncle to Henry, has vowed to end what his brother began. While the threat to England's throne reignites, the French king seeks to retake any and all remaining occupied territory in his country, Thomas Lancaster plots to take the capital, and William must attempt to bring Henry back to the Tower of London.
