Six-Legged Lions and Hemisphere Migration
This was a paperback book I read as a teenager in the 1980s, possibly early 90s (borrowed from my now dead aunt and uncle).
I remember the society having to regularly migrate from one hemisphere to another due to the (I believe) the sun/star being too close and making the closest hemisphere at the time uninhabitable.
There was a multi-decade (century?) lull between migrations, where humanity prospered, but they often had their factories (which they took on their migrations) fall into disrepair.
The biggest thing I remember about the book was the threatening six-legged lions out in the wild that the MCs came across during their attempt at the current migration to save humanity.
Any thoughts on what this book might be is greatly appreciated. I’d love to read it again! ❤️
