It begins slowly in the first installment of The Sin Collector.  The realization that Liliana, upon finding her own people, is facing a war.  This song easily represents the almost calm beginning of that realization.  Being nearly done with The Sin Collector sequel I can drop the teaser that the body count grows quickly, and the war, the genocide of the Collectors, becomes much more sobering to everyone involved.  Be sure to read Book 1, so you as the reader, are also prepared for the battles that await.
