H.D. Carlton Books

H.D. Carlton built her career the indie way: self-publishing dark romance, finding her readers directly, and refusing to sand down her edges when the audience arrived. Satan's Affair introduced her universe in 2021, but it was Haunting Adeline, released the same year, that detonated. The book became a BookTok fixture, the kind of title people post about with shaking hands and a content warning list longer than some prologues, and it carried Carlton to New York Times, USA Today and international bestseller status. Not bad for a book plenty of retailers initially would not touch, and a useful reminder that readers, not gatekeepers, decide what dominates the charts now.

What defines Carlton's writing is total commitment. Haunting Adeline is a stalker romance in which the stalking is not a metaphor, and the hero, Zade, a vigilante who hunts predators and traffickers while obsessively pursuing the heroine, is never defanged for the reader's comfort. Her books run on gothic atmosphere, generational secrets, true crime texture and a pitch-black sense of momentum. Adeline herself, a writer who inherits her great-grandmother's manor and discovers her diaries, gives the duet its haunted-house spine, two obsessive love stories separated by decades and stitched together by one unsettling house. Carlton writes cliffhangers with real malice, and the gap between the two Adeline books radicalized an entire cohort of readers into preordering everything she touches.

The Cat and Mouse duet, Haunting Adeline and Hunting Adeline, is the core of her universe, with Satan's Affair as a companion, Where's Molly arriving in 2024 and Phantom in 2025. Her next release, My Dreadful Darling, is due in September 2026, and the preorder chatter suggests her audience has only grown since the Adeline days. The books interlock enough that dedicated readers treat the whole universe as one long story, though the duet stands perfectly well on its own if you just want the main event.

Let us be direct about heat and content, because with Carlton it matters more than usual. This is a full 5 on our spice guide: explicit, boundary-pushing and central to the story rather than decorative. The content warnings are equally serious: stalking, dubious and non-consent, sexual assault, human trafficking in the second book, graphic violence and gore. Carlton publishes her warnings prominently and means every line of them. If that list gives you pause, trust the pause and pick something gentler; the book will still be there later. If it does not, you already know exactly who you are.

Carlton is not a fantasy author, and we will not pretend otherwise. She is on this site because the overlap between romantasy readers and dark romance readers is enormous, and because her brand of obsessive villain romance energy is the contemporary cousin of the genre's darkest fae courts. Readers who love a morally gray love interest in fantasy and want that dial turned to eleven without a magic system in the way frequently land on Haunting Adeline next, so consider this entry a signpost with a warning label stapled to it.

Start with Haunting Adeline, but only after reading the content warnings, and have Hunting Adeline within arm's reach before you hit the ending, because the cliffhanger is infamous for a reason. Satan's Affair works before or after as a companion piece, and Where's Molly and Phantom reward readers already invested in the universe. If you want this emotional intensity with fantasy worldbuilding wrapped around it, our dark romantasy trope page collects the closest genre equivalents.
