51 Reasons [CountryHumans Apocalypse Fanfic]

Area 51,
It had been the center of attention for months now, all starting with a single petition to raid it.
America of course was Enthralled by the idea, he had always been a thrill seeker so this was his 'cup of tea'

But what if Area 51 was secure, not for the safety of whatever was in there, but for the safety for us outside,
What happens if America doesn't come back? If great powers die? If the world starts to crumble away leaving very few left.
Are New Zealand, Australia, Ireland and Germany able to save everyone, even if it means giving up their identity?

[Disclaimer]:
This book will involve heavy topics including, character death, depression, survivors guilt, identity crisis and possibly more, a trigger warning [TW] will be posted at the start of a chapter if there is anything that may unsettle readers.
I hope you enjoy
