From Wikipedia

The Last Light of the Sun is a 2004 fantasy novel by Guy Gavriel Kay. Like many of his books, it is set in a world that draws heavily upon real times, events, places and people. In this particular book, the period is the Viking invasions of Saxon England. The story concerns a young Erling's attempt to prove himself as a warrior, his father's attempts to make amends for his mistakes, a young prince searching for revenge and a King's attempt to transform his realm into a more civilized one that will resist attacks from the Erlings forever. The books main themes are revenge, violence, the passing of an era, clash of cultures, and love — especially between father and son. The Last Light of the Sun is set in the same world as Kay's The Lions of Al-Rassan and The Sarantine Mosaic novels, taking place after the Sarantine Mosaic but before Lions.

From Publishers Weekly

In this wonderfully imaginative historical fantasy from Kay (A Song for Arbonne), seemingly random deeds connect Erling (Viking) raiders and Anglcyn (English) and Cyngael (Welsh) princes: If only Bern Thorkellson hadn't stolen that horse in a desperate act of vengeance against his sorry fate; if only Dai ab Owyn hadn't stepped outside the safety of Brynfell right at the moment when the Erlings attacked; if only Ivarr Ragnarson hadn't been born ill-formed and downright cruel; if only Aeldred hadn't been king of the Anglcyn; if only Thorkell Einarson had murdered only one man and not the second; if only Alun ab Owyn hadn't stepped into that pool on a moonless night and seen the Queen of the Elves in procession. At first glance, each individual's act appears to be a normal human response. It's only later, as the characters' paths cross, that the pieces come together to weave a dazzling tapestry of conjoined fates. Solid research, filtered through vibrant prose, serves to convey a sense of how people really lived and died in Viking and Anglo-Saxon times and how they might have interacted with the realm of magic on a daily basis. Readers of lighter fantasy should be forewarned—the novel contains a lot of gruesome killing and the fairy world plays a relatively minor role, as do women.
