Overview
A complete trilogy by Robert Holdstock: Celtika (2001), The Iron Grail (2002), and The Broken Kings (2007). It follows a young, still-maturing Merlin alongside Jason and the surviving Argonauts of Greek myth, folding Celtic and Greek mythic traditions into one continuous story of resurrection, memory, and the Otherworld. Merlin, ageless and still learning the scope of his own powers, travels with Jason's crew from the Greek-myth world into Northern Europe's Celtic Otherworld in search of the dead, weaving Holdstock's long-standing fascination, seen throughout his Mythago Wood sequence, with buried, layered mythology into a single continuous narrative spanning centuries and civilizations. The trilogy was recognized within French science-fiction and fantasy circles, with Celtika shortlisted for the Grand Prix de l'Imaginaire.
