An outstanding sequel to the other 'Oathsworn' sequels (the series is now up to number four).
It's a good, gripping story, rich in detail and with plenty going on, both outwardly and inwardly. Many of the characters, especially our hero, get their personalities developed very satisfyingly. We really sympathize with them, through the good times, the battles to survive and the inevitable bad times.
As number four in the series, you might expect the story to run a little short on steam, but that is not the case here. The area and distances of the Viking world covered (early 'European' Russia) is more compact, the story better for it and I for one, am looking forward to the next book.
With this 'Oathsworn' series and Giles Kristian's excellent 'Raven' series (only two in paperback, one in hardback as yet), there are now some serious challengers to Bernard Cornwell's place on my bookshelf. Can't say fairer than that.
