Re: Spirit Walk duology....
The plot threads from Spiritwalk are wrapped up in short order in Full Circle. I don't think it would be much of an issue if you didn't 'get' the references.
I've read both of the SW duology and my life is noticeably worse for it !
Soon oh soon the light, Pass within and soothe this endless night, And wait here for you, Our reason to be here...
