I'm planning to publish my first eBook and have been researching different ebook creation services (https://www.tangence.com/Ebooks.php). There seem to be a lot of options, but it's hard to know which ones are actually helpful for formatting, layout, and overall quality.
Has anyone here used these services before? I'd really appreciate hearing about your experience, what features were most useful, and anything I should avoid before getting started. Thanks in advance!
