Got an ad for a book that doesn’t exist?

Hello fellow readers!

I'm hoping someone can either give me some insight on this or help me figure out what's going on. Yesterday I was scrolling through social media and I came upon an ad for a book called "Hear the Dead" by an author named "Bailey Alexander."

The premise seemed super interesting and right up my alley, and so I thought I would put it on my TBR list. However when I clicked the link in the ad it took me to a different book on the website of the publisher.

When I tried to look the book up elsewhere, I could not find any evidence of its existence, nor could I find any information about the author.

I screenshotted the ad which you can see in this image: https://i.imgur.com/WfLqbEa.jpeg

The publisher was Sourcebooks Landmark.

My initial theory was that maybe the ad for the book was run early by accident, but normally books that aren't being advertised yet will still have listings on platforms like Goodreads as placeholders, but I can't find a listing for it at all, nor can I find the author.

Any advice or suggestions on what might be going on would be super helpful! If the book isn't real, why did I see an ad for it? If it is real, why does it not seem to exist anywhere? I would really like to read it if it does exist, even if it doesn't come out for a while.

Thank you!
