I'm reading. Thinking out loud...
I think I need to inject something more about/of Roget into the first paragraph of Seven.
Maybe..."They came to be in...was at once horrific and magnificent. Roget saw it all." Or something like that. It would remove the long paragraph from strict exposition. I think. I DON'T KNOW! Just don't know.
I'll keep refining, but first, back to Amy going off to work, with Roget at her side. Complete the chapter, then edit again. And again. And if necessary...again.
