On the Grimfens Low Road.
From publisher blurb:
"Why is it that even armed patrols shun the monoliths atop Devil's Hill? What secrets lie amidst the crumbling stones and burial mounds? Are you an Adventurous soul? Would you risk all against vile spirits, dark alfar, grim witches, two-headed giants and acid-spitting drakes? Brave the mystery of the Fairie Ring and uncover secrets old and new, of this world and, quite literally, out of it. The action-packed sequel to The Lejendary Road, by Jon Creffield."
