Many books often challenge the famous saying that advises people not to judge a book by its cover, and the Haunting Adeline series by H.D. Carlton is one such exception to the rule.

The covers of both books are striking monochromatic imageries of grim elements like skulls, spiderwebs, and moths—all highlighted by splashes of crimson. This visual warning is further elevated by the first book’s GoodReads summary, which proudly declares that the series’ first book was once banned on Amazon due to its triggering content.
