If you've read other 'promote your stories' then you'd know they mostly all work in the same way. But in case you haven't read any them I'm going to explain how this will work.
How it works:
There will be a chapter titled 'form', on this will be a form for you to fill out with details of your book. Within this form there will be question about if the book is mature and includes elements of LGBTQ+. Please specify if your book is mature and why just to ensure no young children read a book that isn't suitable for them.
This form can be completed and posted within the comments.
After that I'll read your form, find your book and promote it within a chapter.
Within the form there will be a section for a short summary, I suggest you make this interesting to engage other readers.
