1295 AD. The Christian empire in the Holy Land lies in ruins.
Returning to Paris, Templar Knight Will Campbell is at a crossroads. He has sworn to uphold the principles of the Anima Templi, a secret brotherhood within the Order whose aim is peace - but peace seems ever more impossible.
The Temple has forged an alliance with Will's enemy, King Edward of England, vowing to help him wage war on Scotland. This pact against his homeland strikes at the core of Will's faith and allegiances, while his growing estrangement from his daughter, Rose, leads her into a dangerous affair.
Will now faces a bitter choice: to stay with the Temple and fight another war he doesn't believe in, or to break his vows and forge his own path to peace - even if that too means fighting - for the Scots.
Soon caught up in bloody conflict, Will is unaware that an even more ominous threat is rising, for there is a warrior king on the throne of France whose desire for supremacy knows no bounds and who will stop at nothing to fulfil his twisted ambitions.
The fight for the Holy Land has ended. The Temple's last battle has just begun.
