Four Teens, One Month

There is a friend group of four; Zara Rosewood, Alden Frostfell, Ophelia Sunsinger and Jade Brightstar. Their dream was to live all togheter, so they recently did. But one day they come to know that exactly in a month there will be a catastrofic apocalypse, that will cause a storm that would make the Earth explode. There will rain everyday, but not a normal rain, but a radioactive rain. They don't know what to think, what to say to eachother, but surely they didn't want to die. They figured out that there's a way to save the world from this apocalypse and therefore they can only put it into practice and hope that it succeeds. Will they come out victorious from this adventure?
