Where do I start...this is a masterful combination of world building, science fiction, mixed with the past and legend, a complex setting up of a story that has a follow on novel, maybe the setting up of a series. This is by a new writer to me C.N. Lesley, and this is a magnificent but horrific novel.
The legend, that of Arthur, and Avalon. Characters from the famous stories of the past...yet this is set many generations into the future, and within it the story builds but doesn't really become clear until the last.
The earth, the surface world, with forts and the people still using horses for travel, with Dukes who rule as if in days past when fiefdom was commonplace. In fact, the way they live appears to reflect the medieval period of history...but then there are Submariners, a technologically, highly advanced and apparently self sufficient group of beings, to which Arthur belongs, and so it becomes apparent, a post apocalyptic world, maybe a distopian society. Neither seems to like or trust the other. Then enter the priestly class, those worshipped by land dwellers, the Harvesters or Nestines, and these have the ability to travel through sky and space...but as you find are not exactly human. Then there is an ethereal persona or is it a computer that communicates and gives information to Arthur. Almost a tease as bit by bit the creation of this timezone unfolds, the history is finally revealed, the future...if there is to be one needs a hero...and Arthur it seems is being groomed, but for what?
There are things in this story that amazed me, there are continuous links to the traditional story of Arthur known to many over the generations, yet this is a young man who is affected by memories and dreams..are they past, present or future, guiding him to some event or destination or warning him away from such. The story doesn't leave you on a cliff hanger...and yet it reveals enough to horrify and definitely want to know more and at the point where you realise there is a lot more to come and you want to know the conclusion...or you may wish you hadn't wanted to know it. There's a fight to be had, for knowledge to be passed on, for alliances to be made and for enemies to work together.
This is not a book for children in my opinion, definitely adults and even some YA's may struggle...actually there are parts where I think it may give sensitive adults some unpleasant dreams.
There is a very intelligent mind creating this story, it is well thought out and I think this has been on the drawing board for a long time.
This has the quality and impact of a classic, a quest and a struggle for good to overcome evil...and I seriously compare this to Tolkien and Pratchett in one way, but twisted with the times of legends of Arthur and Merlin and Excalibur and now I'm wondering if Shadow is linked to The Lady of the Lake within the submarine world of Avalon.
I think it would make a tremendous film if detail and storyline is kept too.
I highly recommend this story to the intelligent reader. I happily give it 5 + stars.
