help I really wanna read good omens fanfics, but like not the one shot kind just like a consistent one with a singular story line-

also I don't know if a should write a good omens fanfic or not, and if I do I don't know whether it should be a one-shots book, a fanfic, or both, and if both which one to write first and how long y'all would want each chapter to be-

y'all please help meeee
