Usually a science fiction and fantasy author, Lawhead goes with a bit of straight historical fiction here. The fantasy style still fits as we get an action adventure romp around the ninth century with a good dose of mystical Irish Christianity. The plot is fairly ordinary for this sort of this: inexperienced monk travels, captured by and joins Vikings, then various bits of scheming in the east. The settings are good though, although the action does tend to skip large distances, we get a reassuringly detailed description of life in an Irish monastery, life on a small Scandinavia homestead, visiting Byzantium, and so on.
The characters and dialogue too are above par for this sort of thing. Or the main character anyway – there’s a side line throughout of the staunchly Christian hero Aidan struggling with his faith. This may not be to everyone’s taste, but it does add another (moral) dimension to the book above and beyond what other historical fiction authors like Bernard Cornwell or Tim Severin have done with similar stories. It kind of cool to have a hero who does actually change in outlook gradually throughout the book.
The ending was a little unsatisfying. Aidan fighting with his sense of Christianity in the face of suffering and corruption. It all gets tied up in the last few pages and the epilogue, but we don’t really get to see the new found contentment – it is rather briskly narrated to us. It’s a shame after all that (slightly depressing) self-reflection to basically just tag on a happy ending in a page of epilogue. Again the religious element may not be to everyone’s taste (or so it appears on Goodreads), but it does add some extra depth to the character that the book would be a bit flat without.
