I like how you've included an index in the sample chapter. It shows what else is in the book. How did you generate that? What tools did you use to write the book?
In actual fact: - I wrote the first half of the page in Apple pages - I couldn't cross-reference so I moved to Word for Mac - This worked well, but I couldn't export the PDF with internal links - I converted to LibreOffice - This exported with external links
To create the sample, I then opened in Preview, deleted all the internal pages, dragged in the "call to action" page, then saved.
LibreOffice worked well for the most part, although there were a few little funky things that didn't work how I wanted them to (e.g. justified text puts extra spacing between letters as well as words. Also, indexing a word sometimes makes the alignment go all screwy, for some unknown reason)
