@Warlordess There are many Pokrshipping writers who don't get a deserved Response. So, a shout out book, is like, you give your name, your story theme etc. And you'll get a shout out, and more people will read the book, and youll get a better response.
I dont really know if this idea will work. I hope that it should, because talking about myself, I'm not a famous writer on any site. So I have counted number if response.
