Why EPUB converts so cleanly
An EPUB is a structured package: each chapter is its own document, and the spine records the order readers move through them. VoiceYourNovel reads that structure directly, so the audiobook's chapter list, titles, and boundaries match the ebook without manual cleanup.
Front matter and back matter — title pages, copyright notices, acknowledgements — stay separate from the story chapters, so you decide what gets narrated and what stays silent.
