I simple terms, the premise of the story is based on the belief that the ensuring the very long term future of our species would be enhanced by colonisation and partial migration to another planet.
The question that arises when considering colonising another planetis is, why do we mainly concentrate our efforts on the search for a ready made off-the-shelf and implausibly distant candidate?
We now understand how living conditions naturally occurred on Earth and already possess the technolgy to start trying to replicate that by re-engineering a planet in our very own solar system. Why not make this the main thrust of our efforts.
Our nearest two planetary neighbours are Mars and Venus. Studies show that Mars appears sterile, inactive and lacking the critical mass required to generate the gravitational pull to retain an atmosphere. Venus ison the other hand, is almost the identical size to Earth, has a super-abundance of atmosphere, albeit completely toxic, and is anything but inactive, so I chose Venus for the storyline.

The usual thing really. Tried sending my manuscripts to agents and publishers but had no interest so it was publish independently or not at all.

I started writing in my late fifties and then only because of a storyline that came to me out of the blue that I felt inexplicably compelled to try and capture.
As there was little or no chance of getting anyone to write it for me I felt I had no option but to try my best to bring the story to life.
And that is the point for me, I do not consider myself a 'writer', just a storyteller and if I am lucky enough to get inspiration again as strongly as happened with 'Venus', I will write again.
The imprtant thing for me is the belief and hope that one day, possibly long after my lifetime, the story will find its way into the public consiousness and be part of human inspiration to develop a planet within our Solar system. Our future as a species may depend on it.

I was born in India and lived in there up to he age of 7 when my family emigrated to the UK.
I believe this affected my writing because even as a young child in India, I witnessed and understood the deep divisions between those who had nothing, the many beggars on every street corner, and those who had more than they needed and who daily passed the starving an the dying in their expensive limousines, completely ignoring them with a form of selective vision.
Although the contrast was not so stark in the UK it was stil here but practised in a far more subtle way. Here, as in many Western countries, they have learned that the wealthy minority cannot just simply ignore the poor without consequence so the have moved on to the next stage. Now we the have the finely honed political art of acknowledging the problem sincerely, as if acknowledgement on its own is enough without deeds to rectify the problem.
This femerged as subtext within the Venus storyline.
Sadly, like virtually all countries in the world, the decision makers are either from the wealthy sectors or are finacially controlled by them.
Either way, the systems are firmly in place to protect the privileged minority and manage down the hopes and expectations of the rest.
History has shown over and over again that this prevarication delays but enhances the eventual inevitable corrective backlash.
