Margaret Elphinstone's The Sea Road, and found it enjoyable, both as a novel, and as a believable depiction of the world at that time.
I've now been using the Christmas break to catch up on the first novel she ever wrote, Islanders, derived from her own experiences of living in Shetland, which included bird-watching on Fair Isle and doing archaeology at Barbara Crawford's Papa Stour dig. Both of these islands feature in the novel, which is mostly set on Fair Isle in the twelfth century. It's an accomplished novel, introducing a range of likeable and (from a modern point of view) believable characters, and has some good ethnographic descriptions of the daily life and grind on a small island where the diet is definitely not for vegetarians. There is some violence, but much less than you would expect, and overall the picture is rather cosy, despite the harsh living conditions. It's very much a woman's view of the late Viking Age. There is little or no saga pastiche (the downfall of many other 'Viking' novelists), but the author rather skilfully weaves in lots of allusions to both sagas and poetry, some obvious, some less so, showing that she has done her homework, both in reading the literature, and in understanding how it might have worked in that period. It's a satisfyingly, but not excessively, long book, and the end leaves you wanting to know more - unfortunately Elphinstone never wrote the sequel.
So, the overall verdict is a good read with which to while away the long winter evenings, even if you are allergic to 'Viking' novels.
