I've always found it believable when a major discovery creates fear before hope. If something could change aging, power, and society, people would try to study it, hide it, or own it. That's one of the ideas behind my sci-fi novel First Light Rising. Do you like sci-fi where the real danger comes from how people react to the discovery?
In my sci-fi novel First Light Rising, I wanted to look at immortality less like a cool superpower and more like a problem nobody is ready to handle. If one person stops aging, it's not just personal anymore. Governments, scientist, corporations, and rich people would all want access or control. Do you think immortality stories are more interesting when they focus on power instead of fantasy?
What happens if one ordinary person simply stops ageing and the rest of the world finds out?
That question sounded simple when I first started thinking about it. Then came governments, science, inequality, politics, isolation, and a much bigger question about humanity itself. Somewhere along the way, that thought experiment became First Light Rising.
