Cendrillon copied the book's title - maybe it was available new, if you ordered it - and the scribblings on her notepad, carefully put the book away, and kept looking. The stars, as they looked, seemed like an interesting subject, at least - it would drive home how different the world looked before the Glorious Appearing, without touching subjects like cosmology where she'd have to explain to her charges that entire fields of knowledge had been made obsolete by the Second Coming.
Sadly, any sort of direct astronomical observation would be pretty much impossible; with the moon giving as much light as the old sun used to (OOC note: This is actually in Kingdom Come. Seriously, no more stargazing?) the sky was ever a varying shade of blue, with the occasional tint of crepuscular red during moonless nights. Cendrillon wondered that the images of a dark sky would scare the kids, or be too far out from their experience.
She tried to imagine standing on top of her cabin, the dark sky above her with ten thousand points of light, each a different sun, maybe with different worlds going around it. For just a moment, after she closed her eyes and placed bright spots in the field of view of her mind's eye, something between the bookshelves shimmered.
There wasn't much in the way of post-Glorious Appearing books on astronomy, but Cendrillon made it home with a book of images from the Hubble Telescope (with new cosmology annotations) and one about the American triumph that had been the Space Race. She mostly wanted the pictures, anyway.
