Hi, the website you provided doesn't show the ISBN. We need a webpage showing the ISBN/ASIN and other book data to validate the info and if available we need it for the cover image. It should be non-bookseller site (Amazon & AbeBooks excepted), so from the publisher, library or another acceptable site: https://help.goodreads.com/s/article/..., if you have the book, we can use a scan/photo of your copy for the cover and the page with the publication information (you can upload a scan/photo of your own to the "more photos..." section of your profile (https://www.goodreads.com/photo/new) in the browser, not the app), then copy the link here and a librarian can add it. Make sure you state the source of the photo in the text and that your account settings are public (not private).

Thanks for the info. The website has been updated and now shows the book ISBN https://www.bryantcallahan.com
All the book details, including the ISBN, are also located on the Substack Title page, visible here (if you need a second source)

Description: When Dr. Emélie Desjardins, a disgraced cosmologist with a fragmented consciousness, is recruited into a proxy war between Earth and a rogue AI on Mars, her expertise in gravitational anomalies links her to Origin, a drug that allows users to teleport through a network of quantum gates linked to a parallel reality known as the Manifold. As Emélie ventures deeper into the Hesperides Cartel’s web of corporate espionage and interplanetary conspiracy, she discovers Origin's true purpose extends far beyond drug smuggling. With each subsequent Jump into the Manifold, Emélie is forced to watch the line between truth and deception dissolve as she faces the possibility that her own past may be the key to preventing an interdimensional war.
