From the burning plains of Syria to the filthy backstreets of Paris and London, Brethren is the story of Will Campbell, coming of age in a time of conspiracy, passion, politics and war. Will longs to become a Knight Templar, but first he must serve as an apprentice to the foul-tempered scholar Everard, a man of dangerous secrets.
Meanwhile, a new star is rising in the east. Amir Baybars has fought his way from slavery to become a fearsome commander, driven by an unquenchable desire to free the Holy Land from the European invaders. A stunning, epic novel of war, savagery and heroism.

This is the epic second novel in the million-selling Brethren trilogy. It is 1274 and in the fortified city of Acre, the last major stronghold of the Crusaders in Palestine, an epic conflict is beginning. Will Campbell is a Templar Knight, trained for war, but as a member of the mysterious group known as the Brethren, he is also a man of peace. After years of bloodshed the Brethren have helped create a truce between the Christians and Muslims. But there are those on both side for whom peace is not an option. As war looms, Will is torn between his oath as a Templar, his secret role in the Brethren and his duty to Elwen, the woman he loves but is forbidden to marry.

It is 1295. The Christian empire in the Holy Land lies in ruins and Will Campbell has barely escaped with his life. After years of fighting in the desert sun - and secretly working for peace with the Brethren - Will returns to Scotland to find his homeland under attack by King Edward I of England. Soon caught up in a bloody conflict, Will is unaware that an even more ominous threat is rising. A warrior king on the throne of France has a desire for supremacy and will stop at nothing to fulfil his twisted ambitions.
