Still at the inbetween stage

I set myself a target to start writing again in earnest on May 1st, rather than just dabbling with the new novel. The reason I've held back is that I am limited on writing time and wanted to give But First Maintain the Wall all my attention and not to rush through the final stages. The novel has been read by the professional proof reader, and I've made all the amendments. I have changed the document to a book sized file and set everything out as I want it to be when it goes to print. This includes acknowledgements, an introduction and the copyright page.
The next job is to re-format again, in order that the novel can be read as an e-book. For this the document is  put back to A4 size and I have to choose from a limited range of fonts. The fancy chapter headings have been changed back to Arial. With electronic books being read on various devices of different sizes, I can't see exactly how my words will look on a screen and so now each chapter has a page break so they will always start on a new page. I've added a contents list and hyperlinked it. What is hyper-linking? It means that if the reader wants to go to a particular chapter they can click on that chapter in the contents and go directly to it.
So, what is stopping me from publishing my fourth novel? I am waiting on the cover designer who had some other work to complete first. She's working on my cover now and I've seen the background, so hoping the figure will be added very soon and then it's just the words to go on. I can't wait to see the finished sample.
I'm hoping that within the next week the files will be sent to the printer and proof copies of But First Maintain the Wall will be on their way...
