The flame bearer - Bernard Cornwell (The Last Kingdom #10; First UK edition)

From the day it was stolen from me I had dreamed of recapturing Bebbanburg . . .

Britain is in a state of uneasy peace. Northumbria's Viking ruler and Mercia's Saxons have agreed a truce. And so England's greatest warrior, Uhtred of Bebbanburg, at last has the chance to take back the home stolen from him so many years ago, now held by his scheming cousin.

But Uhtred has made many enemies, sworn many oaths that could distract him from his ambition. And new threats arise as Constantin of Scotland seizes an opportunity for conquest and leads his armies south. Britain's precarious peace threatens to turn into a war of annihilation.

But Uhtred is determined that nothing will keep him from his birthright. He is the lord of Bebbanburg and will muster the skills he has learned in a lifetime of war to make his dream come true.
