Butcher & Blackbird isn't just dark romance. It's dark romance that makes you laugh while two serial killers flirt over a body. The reason it's hard to find readalikes is that most dark romance takes itself seriously, and most funny romance doesn't go anywhere near this level of moral depravity. The overlap is tiny.
We pulled books that hit different combinations of what makes B&B work: morally bankrupt characters you root for anyway, banter that carries the romance, villains as love interests, and tonal whiplash between violence and humor. Some of these are fantasy. Some are contemporary dark romance. A few are closer to horror. Not all of them are funny, but all of them feature people who have done terrible things falling for each other without apology.

Start HuntingDen of Vipers by K.A. Knight
Roxy gets handed to four crime bosses to pay off her father's debt. That's the setup. What follows is violent, explicit, and completely unbothered by conventional morality. The four MMCs are possessive to an absurd degree, and Knight doesn't soften them. They're killers. Roxy matches their energy instead of cowering, which is the only reason the dynamic works. This doesn't have B&B's humor. It's darker, meaner, and the spice is relentless. But if what you want is romance between people who should probably all be in prison, and you don't need anyone to be redeemed, this delivers without flinching.
Nevernight by Jay Kristoff
Mia Corvere trains at a school for assassins, driven by revenge. The voice is what sells it. Kristoff writes with a sardonic, footnote-heavy style that undercuts the darkness with wit, similar to how Weaver uses humor to make the violence in B&B palatable. Mia herself is smart, lethal, and operating with a moral compass that points wherever she needs it to. The romance is secondary to the revenge plot, and the love interest situation across the trilogy gets complicated in ways we won't spoil. Read this for the tone: dark, sharp, and aware of its own absurdity.
The Shadows Between Us by Tricia Levenseller
Alessandra's plan is simple: seduce the Shadow King, marry him, murder him, take his kingdom. She announces this on page one. The FMC is not morally grey. She is the villain of her own story and completely fine with it. The court politics are lighter than something like The Cruel Prince, but Alessandra's scheming carries the book. The romance with the Shadow King works because he's equally dangerous, and watching two people who are both planning to use each other slowly fall for each other instead is a specific kind of fun. Low spice, YA-adjacent, but the villain-as-protagonist energy is rare and refreshing.
Hunt on Dark Waters by Katee Robert
Evelyn is a witch who falls through a portal onto a pirate ship in another realm. The captain, Bowen, is supposed to execute her. He doesn't. Robert writes banter well, and the push-pull between Evelyn's refusal to be controlled and Bowen's rigid code gives the relationship friction that doesn't feel manufactured. The fantasy pirate setting is fun without being overly detailed, and the spice is frequent. This is the closest to B&B's tonal balance on this list: dangerous people, genuine attraction, humor that doesn't undermine the tension.
City of Thorns by C.N. Crawford
Rowan enters a deadly competition in the demon realm, and the demon king, Orion, takes a personal interest in her for reasons he won't explain. Crawford writes fast, the pacing never drags, and Orion is the kind of morally grey love interest who does objectively terrible things while being magnetically charming about it. The trilogy burns through plot quickly, so don't expect deep world-building. What you get instead is relentless momentum, sharp dialogue, and a romance between two people who keep trying to outmaneuver each other. Entertaining in the way that B&B is entertaining: it knows what it is and commits fully.
Savage Lands by Stacey Marie Brown
Brexley is thrown into Halálház, a brutal prison camp where fae and humans are forced together. Warwick, a dangerous fae warrior, is both threat and reluctant protector. The forced proximity is literal: they're locked in a nightmare, and the tension between them builds under conditions that strip away any pretense. Brown doesn't sanitize the setting or the characters. Warwick has done terrible things and will do more. The possessive streak is intense. Five books is a commitment, and the series takes detours that test your patience, but the central dynamic between Brexley and Warwick stays compelling throughout.
Gideon the Ninth by Tamsyn Muir
Necromancers. Swords. Skeletons. Gideon Nav's internal monologue. If B&B's appeal is two unhinged people circling each other while surrounded by death, Gideon the Ninth does that with a completely different aesthetic but the same tonal DNA. Gideon is funny in a way fantasy protagonists rarely are, crass and self-aware, stuck serving Harrowhark, the necromancer she despises. The deadly trial structure forces them together. The humor cuts through deeply creepy, gothic horror. No spice, but the tension between Gideon and Harrow is the kind that makes you forget romance has anything to do with physical contact.
The Serpent and the Wings of Night by Carissa Broadbent
Raihn has done terrible things. The book doesn't hide this, and Oraya doesn't forgive them easily. What connects this to B&B isn't humor. It's the willingness to let both leads be morally compromised without rushing toward redemption. Oraya makes ruthless choices inside the tournament. Raihn's past gets worse the more you learn. The romance builds inside that darkness, not in spite of it. If you want the "two dangerous people choosing each other" thread from B&B in a high-stakes fantasy setting, with the spice dialed back from scorching to steamy, this is the version.
Kingdom of the Wicked by Kerri Maniscalco
Emilia's twin is murdered. She summons Wrath, a Prince of Hell, to help find the killer. He agrees. She doesn't trust him. She's right not to. The circling in this trilogy is the draw. Wrath is hiding things, big things, and every reveal reframes what you thought you understood about his motives. He's not redeemed across the series so much as contextualized. If B&B's Lachlan Slaughter is your brand of MMC (charming, dangerous, zero interest in being a good person), Wrath operates in that same space with more restraint and higher political stakes. The spice ramps up significantly by book three.
Alchemised by SenLinYu
Post-war. Two people with devastating shared history. Neither of them is okay. SenLinYu writes angst like a knife to the chest, and the enemies-to-lovers here is built on years of genuine harm, not bickering. The power dynamics shift constantly, and neither character holds the moral high ground for long. This is the darkest recommendation on the list in terms of emotional damage. No humor to soften it. If you read B&B for the "two broken, dangerous people finding something real between them" thread and stripped away the comedy, this is what's left. It's excellent, but bring your emotional armor.
