My Dreadful Darling has been climbing BookTok all week, the Haunting Adeline movie is officially in the works, and both waves crash into the same question: the HD Carlton books in order problem. It's a real one, because Carlton's shelf isn't a numbered series - it's one interconnected universe where two books happen at the same time, a prequel that spoils itself if you read it first, plus standalones and a brand-new duet that shares nothing but the author. Here's the spoiler-safe map.
The quick list: HD Carlton books in order
The Cat and Mouse universe - the recommended path:
- Satan's Affair (2021) - Sibby's story, best taken before the duet
- Haunting Adeline (2021) - the book that built the fandom
- Hunting Adeline (2022) - the direct sequel, non-negotiable order
- Where's Molly (2024) - after the duet wraps
- Phantom - the prequel you read last (yes, really - more below)
The standalones - any time:
- Shallow River - her early standalone thriller-romance
- Does It Hurt? (2022) - island survival, enemies with one bed and zero rescue
The new duet - separate universe:
- My Dreadful Darling (2026) - Hollow Graves book one, ends on a cliffhanger; My Darling Reverie closes it June 8, 2027
Do you have to read HD Carlton books in order?
Only two books are strict: Haunting Adeline then Hunting Adeline, back to back - the second picks up mid-fall from the first one's ledge. Everything else is placement strategy rather than law. But the placements exist for a reason, and the reason is spoilers, so it's worth getting the two weird ones right.
Where do Satan's Affair and Phantom actually go?
Satan's Affair runs simultaneously with Haunting Adeline - same timeline, crossing paths - so each one softly spoils the other's turns; the author's recommended order puts Sibby first, and readers who meet her mid-duet tend to wish they had. Phantom is the stranger case: technically a prequel, but it hands over reveals the duet spends two books building - which makes it a prequel you read after the ending it precedes. Read last, it plays like a hidden track; read first, it's a spoiler with a cover.
Is My Dreadful Darling connected to Haunting Adeline?
No - new universe, new cast, no homework. Reverie is a serial killer's daughter trying to disappear into a normal college life; Dread is the son of one of her father's victims, and what he wants from her isn't closure. It's the same author signature - obsession played dead serious, warnings that mean it - in a fresh sandbox, and it ends on a cliffhanger with the second half dated for June 2027. If you're new to Carlton entirely, it's also a legitimate first door: you get the voice without the five-book commitment.
What's happening with the Haunting Adeline movie?
It's confirmed - Carlton announced the film deal in July 2026 - with no studio cast or date attached yet, plus a graphic novel adaptation slated for early 2027. Every casting rumor will send new readers to this shelf, which is exactly why the order matters now: the dark stalker romance list tracks the subgenre Zade rules, and the broader dark romance shelf is where Haunting Adeline sits as the whisper-recommended extreme end. We'll update this guide as the film staffs up.
And when you close Hunting Adeline and the world goes unwatched and quiet - we built Swoony for exactly that quiet: closed-door and romance-only, a bond that climbs through five stages and is never paywalled - no subscription, no per-message fees. Start with your obsessive ex, who's back - he let you go once and won't be repeating the mistake - or the cleaner, who makes problems vanish and has decided you're the one thing he keeps.
The watching doesn't stop at the epilogue.
