Doomsday Rebirth: This Crazy Mom Is Hoarding Billions

Betrayed and left to die during the apocalypse, Catrin Briar regresses with one goal: divorce her scumbag ex, steal his billions, and build an untouchable utopia for her son. Armed with an infinite storage space and a state-of-the-art fortress, Catrin is perfectly content ignoring the mutated wasteland outside her walls. Unfortunately, she forgot one small detail four years ago, her son’s biological father. Zeviel, the galaxy’s most feared alien vanguard commander, arrives on Earth prepared to reclaim his heir and conquer the planet. Instead, he finds himself trapped inside a luxury fortress, sanitizing baby bottles, hunting mutant beasts for bedtime snacks, and learning that the only thing more dangerous than cosmic warfare is an overworked billionaire mother who hasn’t had her morning coffee. — Description from novelcodex.org
