I finished reading it last weekend and we created characters yesterday (we had planned starting this as soon as the campaign is out). First of all, as Carew wrote, this is a seriously good book. The world is dark and gritty, but full of detailed locations and richly described characters with personal agendas and motives. There's strife and conflict (between celts and saxons, between pagans and christians, amongst celts) giving plenty of opportunities for adventuring. I also like how it guides players in creating rich and detailed PCs. Even though it lacks magical swords, fireballs and looting treasure (this put off some players in my group), the campaign is really epic, as the characters get to be involved in forging the fate of a nation. The last couple of scenarios have the option for introducing some really mythical elements to the campaign. And even though it's a campaign with a strong story, it isn't railroaded, allowing several outcomes for most of the scenarios. The only thing to be noted is, that the campaign doesn't finish the story it starts telling, but according to Loz, there is a follow-up in planning.
