Demon has some interesting additions to the ongoing “Gaea fucks with Scirocco” relationship but is mostly about Gaea getting senile and watching too many old 1950s movies. Varley was clearly enjoying writing the latter part but it dragged for me.

Titan introduced the setting and went through different parts of Gaea. Wizard summarized the basics of this, if you want more details of what happened to Scirocco’s whole crew then they are in there.

Strictly speaking, the beginning and the end of the whole saga. :)

I found the whole trilogy enjoyable, and quite unique. If you enjoyed Wizard, pick up the other two and (re)read the whole trilogy.
