My 33rd Life's The End

For someone like Hazel, who's reincarnated 33 times, life couldn't be more mundane and annoying. But, what would happen if catastrophe wipes out half of humanity and the entire dynamic of civilization has changed due to the appearance of Gods. Portals with other worldly creatures pop up everywhere and systems are given to each human being in order to fight off the coming of The End. The God's will only allow Earth to exist, if the people are deemed worthy to survive. Is Hazel's reincarnation the key to Earth's survival or will the Earth's demise be her chance to finally rest in peace?
