"Such a strong bond of friendship grows between master and slave, that when the Vikings set sail for their own lands, Jestyn accompanies Thormod as his blood-brother. But Thormod's homecoming is not a happy one: he finds his father dead - slain by the brothers Anders and Herulf, who have now fled the country. Thormod and Jestyn set out in search of them, following the Viking trade-routes to Kiev and beyond to Byzantium. Jestyn is drawn unwillingly into the Blood Feud, taking up a cause which is not his own and from which, on his part, the spirit of revenge is missing. But the day comes when for Jestyn too the Blood Feud is something personal and obsessive. The action of this novel is set in the late tenth and early eleventh centuries."
