«PRAISE FOR RICHARD CULLEN: 'Richard Cullen's writing is as sharp as the blade wielded by Styrkar, the series' protagonist, who cuts a bloody swathe through his Norman enemies on his quest for vengeance. The books are fast-paced and packed with breathless action. Styrkar is a great heroic creation, and the Wolf of Kings series places Cullen in the top tier of historical action and adventure authors' Matthew Harffy. 'Oath Bound is a terrific novel. Fast-paced and enthralling, the tale of Styrkar the Dane, the Red Wolf, charges along like a Frankish knight bearing down on a defenceless enemy. It's a brutal yet compelling tale, and one that gripped me from the first page to the last. The ending came far too quickly and I am looking forward to seeing what fate has in store for Styrkar as he heads towards an uncertain and dangerous future in the next book' Paul Fraser Collard. 'A perfect example of tight, gritty, character-driven storytelling'»
