With Book 6, the story line as written by Fisher and Bergeron is crossed with the story line as written by Price and Pirosh in their graphic novel-exploration of Fontannelle's early years with SOI.
Some background notes, just because:
Behind our characters on the first cover is a view of the Carrie Blast Furnace at Rankin, PA (near Pittsburgh), taken on a walking tour offered by Rivers of Steel, a non-profit that celebrates the work of the old steel mills in the Iron City.
The second cover features "the old Ford Plant" in Indianapolis, an image taken during a "last look" tour offered by Indiana Landmarks before what had been a manufactury, and later a warehouse for Indianapolis' school corporation, was turned into a retail/residential complex.
The third cover features one of my most contrived settings: the mountain in the distance was shot from the aerial tram that ascends the Sandia Peak above Albuquerque, NM, while magazine boxes comprise the mid-ground structure--with a fair amount of "Photoshopping;" the buildings nestled on the mountainside are mostly fabricated from pixels. The kind of background I had in mind was not something I had a photograph of, so I just made it up. These days that's no so unusual, I guess, what with all the rendering programs available, but I've not used those, and am still stubbornly sticking with, for the most part, imagery actually photographed.
