“An absolute ’must’ for the legions of Marvel Universe fans… With many an unexpected plot twist and turn, The Head of Mimir is a wonderfully entertaining, impressively entertaining, and highly recommended.”
– Midwest Book Review

“The Head of Mimir is a hell of a story, more in line with the epics of legend than anything I’ve read in the Thor comics, but it fits so well with the universe and characters that Marvel have adapted over the decades. Richard Lee Byers clearly know not just the world of the comics, but the original myths too, and manages to weave them together in great ways. ”

“Mimir is packed with action and ideas, many of which come from Norse mythology itself… a book that is not quite fantasy or science fiction, but a mash up of the two genres… and then adds more action that I have ever read in such a book. For readers who enjoy their fantasy full on and nonstop, this will be a great read.”
– SF Book Reviews

“The Head of Mimir is a fun, fast-paced fantasy adventure… this offers a fresh perspective and its own unique take on Heimdall, Sif and the Nine Worlds, while finding a satisfying balance between fantasy and mythology.”

“I really enjoyed The Head of Mimir, it’s an accessible read that clips along at a good pace, but also offers deeper rewards for fans of the source material, whether it be Marvel, the Norse Sagas, or both.”
