The problem with attempting to write hard science fiction is that you really really need to get the details correct. Because there are experts out there who you won't fool, and they'll rip you to shreds if you screw something up.
I haven't even got to that point yet. I may ask some experts to beta read Venus at some point, but that point is still in the future. Right now, I'm just trying to get the first draft down and have it make sense.
And in the meantime, I've redesigned the city and slightly altered some plot stuff. Because the science says I have to.
