Picked up the first 2 books - Winterbirth and Bloodheir - last week.
http://www.amazon.com/gp/product/product-description/0316068063From a review:
In a land very much like medieval Scotland, the Thanes of the South battle against the Thanes of the Black Road (a religious schism) for domination of the land and spiritual salvation. ...

There are a number of characters whose journeys are followed as the plot progresses; Orisian one of the not-so-direct heirs of a kingdom; Gryvan, the King of Kings, ultimate king; and Aeglyss, a half-breed with mystical powers of persuasion and charisma. With a novel of such epic scope, Ruckley does follow more characters but these stood out the most for me. Orisian and his shieldman (bodyguard) seem to be the only survivors of an attack on their family during the Winterbirth celebration. Through their journey, Ruckley is able to reveal and convey the harsh landscape of the “Godless World,” of the story.
The character who worked the best for me was na’kyrm Aeglyss. His combination of dark intentions and charisma reminded me somewhat of R. Scott Bakker’s enigmatic Anusûrimbor Kellhus. Both characters have, at the outset, mysterious backgrounds and a power over men with their words. Though it will take a lot for Aeglyss to match the heights of Kellhus’s character (no small feat for any character), Ruckley has planted the seeds of something very intriguing with him.

Ruckley’s world is a harsh unforgiving place and he shows no compromise to the reader’s sensibilities by illustrating just exactly what this means to the inhabitants. No one is safe in a place where even the simple act of living through tumultuous times can have long lasting consequences. I particularly liked the air of ambiguity that Ruckley gives his characters, they all have good reasons for doing what they do and believe that they are right. Faced with such certainty on all sides, the reader really has to think about what side they will support (if any) and this makes me really look forward to the next book...
