My Apocalypse Ark

Rory is reborn one month before a world-ending torrential downpour. She decisively has her husband, Gavin Cole, abandon his assets and cut off contact with his parents-in-law and younger brother. The two build an indestructible steel Ark. Apocalypse arrives, city submerged. The couple withstands disasters and repels thugs and parasitic relatives. They survive the storm, sailing towards a new world.
