Long Days in Paradise: The First Book of the Shards of Heaven

Jorden has stumbled into a strange land of not-quite human inhabitants, his friend Taf at least human enough in all the ways that matter. Getting home means facing the witch-god Hura, if she exists at all, on the other side of Nowhere. But this is a world of many races run by the spiritual kaedith and financial sarisan, while he is friend to the lowest class species who struggle simply to survive.
