Books like Lights Out

Two serial killers who target other killers meet by accident and start a twisted annual competition that turns into love. Brynne Weaver matched Lights Out's ability to make darkness funny. The tone, the banter, the unapologetic embrace of morally questionable characters.

Both books found the sweet spot where horror meets comedy meets romance. Sloane and Rowan have the same energy as Lights Out's couple. Dangerous people who find each other genuinely delightful.

Weaver's humor is slightly broader than Allen's drier style, but both authors commit fully to their premises without winking at the audience. If you loved Lights Out, Butcher and Blackbird is the most natural companion read. Same energy, different flavor of darkness.

Adeline inherits her grandmother's house and discovers she has a stalker who leaves notes, breaks in while she sleeps, and is absolutely certain she belongs to him. H.D.

Carlton plays the stalker romance premise more seriously than Allen does. Where Lights Out uses humor to balance the darkness, Haunting Adeline leans into the menace. Zade is darker and more obsessive than Lights Out's love interest, and Carlton pushes the content further.

Both books feature heroines who are stronger than their situation suggests. Adeline is not passive, and her relationship with Zade's obsession is more complicated than simple victim and predator. If you loved Lights Out and want the same premise played at a higher intensity with less comedy, this is the escalation.

Alex Volkov is cold, controlling, and hiding a revenge plot behind his stoic exterior. When he agrees to watch over his best friend's sister, Ava, the walls he has built start to crack. Ana Huang writes the obsessive hero with restraint that builds tension beautifully.

Like Lights Out, the appeal is watching a dangerous man become undone by the one person who makes him feel something. The chemistry builds through proximity and resistance. Alex watches Ava the way Lights Out's hero watches from the woods.

With intensity that should be threatening but somehow becomes magnetic. Huang goes easier on the humor than Allen does, trading laughs for emotional depth. If you loved the possessive dynamic of Lights Out but want something where the darkness is more emotional than physical, Twisted Love delivers.

Michael Crist and his three wealthy friends return after years away, seeking revenge on Erika for something that happened when they were younger. Penelope Douglas builds an atmosphere of dread and desire that keeps you guessing about who is the predator and who is the prey. Like Lights Out, Corrupt features a heroine caught between fear and attraction.

The power dynamics shift constantly, and the group element adds complexity that a two-person dynamic cannot achieve. Douglas writes the menace-to-attraction pipeline masterfully. The Devil's Night series that begins here is darker and more intense than Lights Out, with less humor and more psychological pressure.

If you loved the shifting power dynamic where the heroine discovers she is not as helpless as she seemed, Douglas pushes that premise further.

Posy is kidnapped by a dangerous man and given simple instructions. Run. If he catches her, she is his. Cate C.

Wells took the hunter-prey dynamic to its most literal and created something that is both terrifying and absurdly romantic. Like Lights Out, the heroine is not what she seems. Posy has her own strengths, her own cleverness, and her own reasons for engaging with the game rather than simply trying to escape it. Wells writes the tension between fear and desire with precision.

Every chapter ratchets the stakes higher while the connection between the characters deepens in ways that should not make sense but somehow do. If you loved the chase dynamic of Lights Out and want it concentrated into pure adrenaline, Run Posy Run is a short, intense read that delivers.

Lark is running from her past. Lachlan is a hitman with a surprisingly gentle heart. Their paths cross in ways that are both dangerous and inevitable.

Brynne Weaver shifts the dynamic from Butcher and Blackbird's competitive energy to something more protective and tender, but the dark humor and morally gray characters remain. Like Lights Out, this features a heroine who needs protection but is not helpless, and a hero whose dangerous profession makes the romance inherently high-stakes. Weaver writes the vulnerability beneath the violence with real skill.

Lachlan is quieter and more dangerous than most dark romance heroes, and watching him open up to Lark is genuinely moving. If you loved Lights Out's balance of darkness and heart, Leather and Lark captures a similar tone with different emphasis.

Killian Carson is not a hero pretending to be a villain. He is a villain who has no interest in pretending otherwise. His fixation on the heroine is consuming, manipulative, and utterly unapologetic. Rina Kent writes dark romance without guardrails.

God of Malice pushes the obsessive-hero dynamic further than Lights Out does, removing the humor and replacing it with psychological intensity. If Allen's hero watches from the woods, Kent's hero dismantles your life from the inside. This is not for everyone. Content warnings apply liberally.

But for readers who loved Lights Out's dark dynamic and want something that goes significantly harder, Kent delivers. The college setting adds a layer of social manipulation that gives the heroine opportunities to fight back on her own terms.

Anna Zaires's Tormentor Mine is the dark romance readers reach for when they want the Lights Out obsession dialed all the way up. Sara Cobakis is a suburban anesthesiologist whose ordered life fractures when Peter Sokolov, a former Russian operative, decides she belongs to him.

He is precise, lethal, and unnervingly gentle in the same breath, and Zaires writes the push and pull between fear and want with the same nerve Allen brings to her masked-hero fantasy. This is a captor romance in the fullest sense, so the content sits firmly in adult territory, with dubious-consent themes and on-page violence that the book never softens or apologizes for.

Recommended for Lights Out readers who want a morally-gray hero whose danger is not an aesthetic but the entire engine of the story, and who like their tension coiled tight from the first page.

Penelope Douglas built Credence for readers who want their dark romance claustrophobic and unapologetic, which makes it a natural next read after Lights Out. Tiryn Blackwell, orphaned and adrift, is sent to a remote Colorado mountain to live with her estranged stepuncle and his two sons, and the isolation turns the household into a pressure cooker where every relationship curdles into something possessive.

Douglas writes morally-gray men with the same magnetic edge Allen gives her masked hero, and the heat stays high and constant once the walls start closing in. This one carries adult content and taboo-adjacent dynamics that readers should go in expecting.

Recommended for Lights Out fans who liked the sense of a world narrowing down to obsession, and who want a self-contained standalone they can binge in a snowbound weekend.

Sara Cate's Praise pulls the Lights Out appetite for intensity into a different register, trading suspense for a consent-forward power dynamic that reads just as charged. Charlie is drifting after a public humiliation when she stumbles into an exclusive members club and into the orbit of Emerson Grant, its guarded, older owner.

Cate writes desire as something Charlie is finally allowed to want out loud, and the pull between the two of them carries the same obsessive electricity Allen builds between her leads, minus the knife's edge. The spice here is explicit and central to the story rather than an occasional garnish.

Recommended for Lights Out readers who loved the unashamed heat and the emotionally raw heroine, and who want a morally-gray older love interest whose control is a gift rather than a threat.

Danielle Lori's The Sweetest Oblivion is the mafia romance dark-romance regulars trade like a secret, and it earns its place next to Lights Out on obsession alone. Elena Abelli has spent years being the good daughter while her wilder sister gets engaged into a rival family, and then Nicolas Russo, the Underboss brokering the union, sets his sights squarely on Elena instead.

Lori writes a slow burn that smolders for chapters before it catches, and Nico's possessiveness has the same barely-leashed quality Allen gives her hero. Hidden gem because it launched as a self-published indie and built its enormous following almost entirely through word of mouth before wider printings caught up.

The content is adult, with on-page heat and mafia violence. Recommended for Lights Out readers who want a dangerous, possessive love interest wrapped in a slower, more simmering build.

Sierra Simone's Priest is the taboo romance dark-romance readers keep pressing on friends, and it hits the same forbidden-desire nerve Lights Out lives on. Father Tyler Bell took his vows after a family tragedy and has held the line for years, until Poppy walks into his confessional and unravels every rule he built his life around.

Simone writes want as something guilty and consuming, and the tension between duty and desire has the same charged, transgressive pull Allen uses to hook her readers. Hidden gem because it started as a controversial indie release that split readers before slowly becoming a genre landmark.

The content is fully explicit and leans hard into taboo, so readers should arrive prepared. Recommended for Lights Out fans who liked the sense of crossing a line, and who want a morally-conflicted hero whose restraint makes every break more electric.

Cora Reilly's Bound by Honor is the mafia romance that quietly built one of the largest followings in the genre, and it channels the same possessive intensity that makes Lights Out land. Aria Scuderi is a Chicago mafia daughter promised in marriage to Luca Vitiello, the brutal heir to the New York Famiglia, and she walks toward the altar terrified of the monster she has heard about.

Reilly writes Luca as dangerous and territorial in the same breath he learns to soften, and the slow thaw between fear and want tracks close to the push-pull Allen builds. Hidden gem because it started as a self-published indie and grew into a sprawling universe almost entirely on reader loyalty.

The content is adult, with mafia violence and on-page heat. Recommended for Lights Out readers who want a possessive, dangerous hero and a world where every relationship carries a threat underneath it.

Morgan Bridges's Once You're Mine, released September 2023, is the recent stalker romance BookTok pushed hardest at Lights Out fans, and the fit is almost too clean. A woman in need of a dangerous man's help finds herself entangled with someone who has already decided she is his, a tormentor who watches, follows, and narrates his obsession with the kind of possessive certainty that made Allen's hero go viral.

Bridges leans into the falls-first, touch-her-and-die energy that the subgenre thrives on, and the heat runs high throughout. This one carries adult content and heavy stalker themes, so readers should check the warnings.

Released September 2023 as the first book of a duet that ends on a cliffhanger. Recommended for Lights Out readers who want the most direct modern echo of the obsessive-stalker fantasy, freshly published and unapologetic about it.

Rina Kent's Beautiful Venom, released May 2025, is the recent dark romance for Lights Out readers who like their morally-gray hero to be genuinely dangerous rather than merely brooding. Dahlia Thorne walks onto a university campus with a plan to avenge her sister, targeting Kane Davenport, the charismatic captain of the Vipers hockey team, as her way into a hidden campus society.

The plan curdles the moment she realizes Kane's friendly surface hides a predator far more lethal than she gambled on, and Kent writes the trap snapping shut with the same coiled tension that runs through Allen's work. The content is adult, with violence, secret-society brutality, and on-page heat.

Recommended for Lights Out fans who liked a hero whose charm is a mask, and who want a fresh 2025 release from one of the busiest names in dark campus romance.
