As an English teacher and busy mother, writing is not so much a task to be done as a physical need. I think about far-flung galaxies and the magic that is our universe constantly, and to not write it down would be an impossibility.
Lack of sleep it is, then, and space, and sexy, star-crossed romance, and corrupt societies that are far too much like our own.
I'm currently writing book two of the 'Worlds' trilogy. As they say, watch this space, and perhaps enjoy the first novel while we wait...
