The year is 1307. A stranger arrives at a remote cottage in the Galloway hills which belongs to the ‘Widow of Craigencallie’ and her three sons. The stranger sets the brothers a challenge which will change their lives forever. Scorned by his older brothers William and Ian, Thomas Murdoch, a young shepherd, rises to the challenge, heartened by his dream to serve King Robert Bruce. He joins Bruce’s army, who are victorious at the Battle of Glentrool, but this is followed by personal heartbreak, which leads him to a new path at Whithorn Priory, where he trains as a novice. However, his tranquil life is disturbed by the arrival of Ian, who bears grim news of William. Despite their differences, they begin a journey of revenge which leads to the Battle of Bannockburn. But will Thomas be able to manoeuvre his way through the politics of fourteenth-century Scotland to achieve his dreams? Or will he have to decide where his loyalties lie? A tale of ambition, loyalty, rivalry and treachery.
