[Shaedyone]

3 main characters.

2 are friends who grew up together (Male)

1 is a female reporter.

It's spread over numerous worlds.

One is hyper religious
One is hyper secretive.

Rest are normalish.

Close to opening sequence is a company cop/security guard chasing a murderer along a beach with boiling water and multi coloured rocks. He follows them into a outflow pipe.

Anecdotes in the story from main characters childhood. He remembered (he was raised on a world where they banned a inter world internet that connected other world) his world was religious. A band (from a different world) had been allowed to perform in a stadium. At the end of the bands performance a overseeing priest goes down to them and burns the band and himself alive.
Humanity is all dying between 35 to 40 yo (roughly)
The main character is living isolated on a harsh world with a rough or boiling ocean/sea. It's a colony world and under a shield from extreme wind

People can vote in a lottery to select who to resurrect

People in this lottery are sunk in special coffins in this world with the boiling/rough sea/ocean.

There are platforms on this ocean to monitor and look after these coffins.

These platforms are controlled by one "conditioned" human aided by 2 clones and a lot of automation

The female reporter adds stories to the galactic internet about people she interviews, and AI suggests people and worlds she could get stories.
