Resistance - The Bravehearts Chronicles

Born to a divided kingdom. Destined to unite it. AD 1286: The King of Scots is killed, leaving no heir. Twelve-year-old Robert Bruce, heir to the great House of Bruce, comes of age amid the bitter rivalry of Scotland's most powerful nobles to claim the vacant throne. The boy is schooled in the arts of warfare and the manipulation of ruthless and violent men, but when the Scottish Crown is bestowed upon Bruce's greatest enemies, Robert travels with his family to England, swearing feudal loyalty to King Edward Plantagenet - known as 'Longshanks'.
But Longshanks's increasing treachery and his brutal attempts to annexe Scotland see Robert turning renegade and returning to his home country. The Battle of Bannockburn lies ahead and a legend is born. This is the story of one man's resistance, and the bravery of a country that would not yield.
