M.D. Lachlan's brooding and powerful tales of Vikings, Norse gods and werewolves have already won praise from, amongst others, Joe Abercrombie, Adam Roberts, Mike Carey and Chris Wooding.With an original and terrifying take on magic, an ability to bring the Norse gods to vivid life on the page, a keen historical eye and a knack for fast-moving and brutally effective plots, M.D. Lachlan's series has won over critics, fellow authors and readers alike. VALKYRIE'S SONG moves the action to Norman England and the Harrowing of the North. An immortal wolf and an immortal woman are on the run, fighting for their lives. They carry a magic within them, runes which flare with power when brought together. But others hold runes of their own, and the runes desire to be united. And when they are, Ragnarok will come.
