I need to get text from an epub

```
from epub_conversion.utils import open_book, convert_epub_to_lines

f = open("demofile.txt", "a")
book = open_book("razvansividra.epub")
lines = convert_epub_to_lines(book)

```

I use this but if I use print(lines) it does print only one line. And the library is 6 years old. Do you guys know a good way ?
