Book excerpt: Vulgar is a Viking boy who longs for the glory days of raiding, pillaging and enormous beards. Life in the village of Blubber is so dull, it's all knitting and goat-herding and yawwwnnn. Vulgar feels it's up to him to introduce a bit of mayhem and chaos, and just as soon as he's finished juggling with elk manure, he's going to relish the challenge.
