I haven't yet had to do much research for my writing. Nothing like, say, a novel in a historical setting where authors like Gary Corby or Christian Jacq are clearly steeped in the cultures they have set their works in.
The people in Ghosts of Innocence have never even heard of Earth, so nothing of our history or culture can have any factual bearing on the story. I had a blank slate on which to craft worlds of my own. The most I had to do was check some calculations on orbital periods, and review the span of space my story was set in against the overall layout of the galaxy, to make sure I wasn't making any blatant astronomical blunders.
Tiamat's Nest is different. It is set on Earth, later this century. A markedly changed Earth, to be sure, but there needs to be some recognizable bedrock to the imaginary places I am building.
Part of the story is set in an ice-free Greenland, where new communities have become established on the newly-habitable land.
So, I needed a map of Greenland.
I set off with naive optimism, thinking it would be easy to find a decent map charting the features buried under the ice.
Search after search soon showed that, to most people, Greenland is a thin ribbon of fjords surrounding a big blank white space. Printed atlases are no better. Most of them cover it at such a small scale they don't even mark the human settlements there today.
Today, I visited the local library, hoping they would have more useful references.
They had some impressive atlases. All of them added precisely nothing to the meager store of knowledge I already had. The librarian tried to help, but told me that they had not long ago disposed of their collection of maps because nobody ever referred to them. The largest nearby bookstore still had a map room, though.
So, off to the bookstore.
I found a section with maps. Nothing of Greenland. I asked at the counter, explaining what I was looking for.
The lady thought for a moment, and remembered that there was indeed a map of Greenland sitting in a back room waiting to be returned because they'd had it so long they decided they were never going to sell it.
Talk about "meant to be"!
So, now I have something to work on. It's still mostly blank in the center, but it is a map with a scale, with existing settlements and other features named. I am now overlaying this with a topographic view I found online showing the true ground level under the ice. I figure that I am safe adding made-up names to features (like the large inland sea which would appear if the ice melted) because the first settlers in this new land would likely have a free hand naming things anyway. Who's going to argue?
