Jupiter #19 has been reviewd by Terry Grimwood on the Whispers of Wickedness site. Of Roadwalker he says:
Roadwalker by Gareth D Jones takes us to another future-primitive society through which an intimidating, enigmatic road has been carved by a mysterious machine. No one knows where it leads, who built it or why. So, cheek still damp from his truelove’s kiss, a young farmhand sets off to find out. This is one of an occasional series but stands alone as a yet another warmly compelling piece.
'Warmly compelling' is good enough for me.
