When author Adeline Reilly inherits Parsons Manor, her late great-grandmother's isolated estate in Washington, she moves in hoping for quiet and inspiration. Instead she finds a house full of secrets — a long-unsolved family disappearance — and the unsettling sense that she is never truly alone. Someone is watching her. That someone is Zade Meadows, a masked vigilante who runs an underground operation targeting human traffickers, and who has become dangerously obsessed with Adeline. As Adeline unravels the mystery buried in the manor's history with the help of her friend Daya, the line between predator and protector blurs into something neither of them can control. Haunting Adeline is the first book in H.D. Carlton's Cat and Mouse Duet, a BookTok phenomenon known as much for its polarizing reputation as its popularity. It is an extremely dark, graphic romance built on a stalker premise and should be approached with its extensive content warnings firmly in mind. The story concludes in Hunting Adeline.

Bridget von Ascheberg never expected to inherit a throne, but when her brother steps aside she becomes the reluctant heir to a small European kingdom, her every move dictated by duty. Rhys Larsen is the stoic ex-military bodyguard assigned to protect her, a man with an iron rule against getting emotionally involved with the people he guards. Forced into constant proximity, the princess and her protector slide from wary friction into a romance that neither royal protocol nor his professional code permits. The second Twisted book trades the first's darkness for a forbidden royal-bodyguard slow burn, following one of the four friends at the heart of the series as she fights for a sliver of freedom and the one person she is forbidden to want.

Aly Cappellucci sees the worst of humanity every shift. As a trauma nurse, she has grown numb to blood and crisis, and she chases the adrenaline she no longer feels at work in the dark corners of the internet — in particular, the videos of a masked man who calls himself the.faceless.man. When a reckless late-night comment invites him to make her fantasies real, she never expects him to say yes. Josh Hammond has spent his life hiding: behind a mask, behind a screen, behind the wall he built between himself and the father whose face he shares. Aly is the first person to see him and not flinch. What begins as a dangerous game between two strangers becomes something neither can walk away from. But Aly has drawn the attention of someone far more dangerous than the man in the mask, and the fantasy is about to turn deadly real. Navessa Allen's viral dark romance is a twisted, darkly funny, and unapologetically explicit story about obsession, control, and the thin line between fear and desire. The first book in the Into Darkness series pairs a heroine with a taste for the macabre and an antihero determined to protect what's his, whatever it takes.

Hunting Adeline picks up in the aftermath of Haunting Adeline, and it does not soften. Adeline has fallen into the hands of the very organization Zade Meadows has devoted his life to destroying — a ritualistic network of powerful men who traffic women and children. While Adeline endures captivity, Zade unleashes everything he is to find her. The novel is split in two: the first half follows the hunt and rescue; the second follows the long, difficult work of recovery, as Zade and Adeline confront what was done to her and turn toward the people responsible. Their bond is tested by trauma, vengeance, and the question of whether either of them can be whole again. The second and final book of H.D. Carlton's Cat and Mouse Duet, Hunting Adeline is an extremely graphic dark romance that deals explicitly with sexual violence, trafficking, and torture. It should only be read alongside its full content warnings.

Sasha is a woman living as a man to infiltrate the Russian military, driven by a single purpose: revenge for the massacre of her family. Her disguise holds until her path crosses Kirill's, her superior, a captain of magnetic charm and flawless exterior who will be the one to introduce her to true carnage. They could not be more opposite, yet they collide under the strangest circumstances, and the pull between them threatens everything she has hidden. Behind Kirill's perfection lurks a manipulative, emotionless monster with his own dark family history and ambitions to rule, and he is as much Bratva as soldier. As Sasha edges closer to the truth about who destroyed her family, she risks Kirill uncovering her secrets, including why she is pretending to be a man, and luring her past the point of no return. With a gender-disguise premise often compared to Mulan, this opener blends military intrigue, mafia power struggles, and a slow, dangerous attraction. It is the first installment of a trilogy and ends on a cliffhanger; it is explicit and built on forbidden, antagonistic chemistry.
