I always found that the Spirit Walk
was sort of like DS9's Abyss
and Demons of Air And Darkness
. The books took place after their relaunch "pilot" titles, but they were of a little bit lighter affair than what their "pilot"'s were, while at the same time still ramping up what was to come (although with Voyager, that ball kind of got dropped with Christie Golden's departure from the series, since it would've been interesting to see where the series could've gone had Golden stayed with the series).
