Haunting Adeline is the book r/DarkRomance points to when someone asks what the genre actually means, and the one they warn you hardest about. Adeline inherits her grandmother's Victorian mansion and realizes she's being watched by a stalker who has no intention of hiding. It's deliberately boundary-crossing, very explicit, and built on dark-romance conventions that depict fantasy scenarios, not endorsements, readers are emphatic about checking the (long) trigger-warning list first. The community is split: some call it a compulsive obsession read, others bounce off it hard. Either way it's the genre's most-discussed title. Note from the threads: it doesn't resolve in book 1, so have Hunting Adeline ready.

Alex Chen, her brother's best friend and temporary guardian, has spent years keeping his distance from Ava. He has his reasons, and they're darker than she knows. The entry point before Haunting Adeline, or the palate cleanser after. Same dark-love-interest energy at significantly lower intensity.
by Penelope Douglas
A girl forced into a Halloween revenge game that becomes something else entirely. Douglas is the author most Haunting Adeline readers cross over to. Dark, explicit, and psychologically complex.

Tiernan De Haas, a young woman adrift after her parents' deaths, goes to live with her stepfather and his two sons in a remote Colorado mountain compound. The isolation makes everything complicated in ways she didn't expect. Same deliberately uncomfortable dynamics as Haunting Adeline. Same trigger-warning culture applies, not for every reader.
by S.T. Abby
An FBI agent pursues revenge while falling for the wrong man. Similar dark-romance energy with a plot-driven backbone that gives it more structure than purely emotion-driven dark romance.
by Colleen Hoover
The psychological thriller most Haunting Adeline readers cross over to. Not dark romance, but the same "I need to know what happens even though it's disturbing me" reading experience.

Book 2 of the Cat and Mouse Duet and the direct continuation of Haunting Adeline. The story doesn't resolve in book 1, Hunting Adeline is where the ending lives. Read them back to back.
Stalking, explicit non-consensual content (detailed), violence, manipulation, and dubious consent throughout. This book requires understanding that dark romance depicts fantasy scenarios not endorsed by the author. Check StoryGraph for the full list before starting.
Yes, book 1 of the Cat and Mouse Duet. Book 2 is Hunting Adeline. The story does not fully resolve in book 1, so read both. They're typically sold together or back-to-back because of the cliffhanger.
Only if you want much darker content. ACOTAR's dark elements (morally grey love interest, court politics) are very different from dark romance's intentional trigger content. Haunting Adeline is frequently cited as the book that defines the difference between the two genres.
