What is being a space girl

I always thought being a space girl was amazing. I could travel through the stars, swim through black holes, go to any planet. Well any planet expect Earth. I thought this until I broke that rule. Earth people, planet earth it's all amazing. they could go anywhere if they just tried to hard enough. they could even love.
Now I have to fight against my mother and her rules. That are insane on my adventure in Earth. If I don't my new friends and everyone else on this planet could die. Now it's my job to protect them from my mistake.
