Hello Quentin, that is an interesting question. Kindle Vella can be used as a tool for authors to gather exposure. Still, we would advise focusing on popularizing your novel "The Dead Giveaway" and your name as an author. More media visibility, add your book to more platforms and use Amazon Sponsored Ad Campaigns. Do a lot of Author Interviews on different platforms, and try being on podcasts and/or video discussions.
Even though readers like to read, visual content is still the best tool for advertising.
But if you have ideas for Kindle Vella, why not try it? You might gather fans from there and redirect them to your novel.
Thank you for your question!
