The Southern Victory series by Harry Turtledove. Follows from the South winning the Civil War up through WWII with the US and Confederates being bitter rivals throughout.

Probably not the best, but I enjoyed the novelization of Star Trek IV. You get to actually see what the probe is thinking from its point of view, which was fun and super interesting.

If I do a Google search and a Reddit thread comes up with relevant info or discussion, I’ll check it out but I have completely stopped browsing and interacting with it.
