Travel Back to the End of the World Before Rebirth

Looking for Completed Apocalypse Novels. Completed, Completed, Completed

I've already read *Global Power Outage*, an apocalypse novel, but I really can't get into other apocalypse stories. Please recommend pure natural-disaster survival stories with no pocket dimension, no System, no zombies, and no superpowers. Nothing still being serialized, because waiting drives me crazy. Thanks, fellow readers.
