I'm also working on a children's fantasy novel. To a lot of people, the fantasy genre doesn't merit the same need for research and hard facts. How can you possibly research a fantastical world of goblins and magic and flying cars? Isn't it all in the writer's imagination?
Personally, for my own novel, I've found myself researching:
- the meaning of names,
- how science can tie in with how my magical devices work (mainly nuclear fission),
- mythological creatures (for example, harpies and pixies),
- and real life settings that I've used as inspiration for locations in my novel (Covent Garden tube station and York Minster, to name but two).
This kind of research adds a reality to our fantasy writing, grounding it to make the imagined world of our novel appear more substantial and believable to the reader.
Before I attempt my next chapter, I have to return to the subject of nuclear fission and power plants. Excuse me while I get my goggles and big rubber gloves.
