This collab is by invitation only. Once I ask you and you write your chapter ask two other people and that will make it grow.
You may write about anything but it has to relate to the chapter before you. So once this collab has gotten to more than 30 chapters, you don't have to read all the chapter. Just simply read the one that was written before yours.
Oh, wait, I forgot something. 50 words or more. Nothing under 49 and under.
