Scythe & Sparrow by Brynne Weaver

My rating: 4 of 5 stars

From the #1 New York Times and USA TODAY bestselling author of the genre-breaking international TikTok sensation Butcher & Blackbird and Leather & Lark comes the final book in the Ruinous Love Trilogy—a friends-with-benefits dark romantic comedy packed with murder, mayhem, and spice.

Doctor Fionn Kane is running from a broken heart, one he hopes to mend in small-town Nebraska, far away from his almost-fiancé and his derailed surgical career. It’s a simpler life: head down, hard work, and absolutely no romantic relationships. He wants none of the circus he left behind in Boston.

But then the real circus finds him.

Motorcycle performer Rose Evans has spent a decade on the road with the Silveria Circus, and it suits her just fine, especially when she has the urge to indulge in a little murder when she’s not in the spotlight. But when a kill goes awry and she ends up with an injured leg, Rose finds herself stuck in Nebraska, at the home of the adorably nerdy town doctor.

The problem is, not every broken heart can be sewn back together.

. . . And the longer you stay in one place, the more likely your ghosts are to catch up.

Characters Backgrounds & Plot Summary

At the heart of this final installment are two deeply scarred and fascinating characters. Doctor Fionn Kane is a man defined by restraint, intelligence, and a quiet intensity that borders on obsessive. Professionally, he is controlled and methodical, someone who has built his life around saving others. Underneath that polished surface sits a heavy burden of trauma and guilt that shapes how he connects with the world. He is not emotionally open, and that distance becomes both his shield and his weakness.

Rose Evans is his complete opposite in presentation yet equally fractured beneath the surface. A motorcycle performer with the Silveria Circus, Rose has spent a decade living a transient, adrenaline-fueled life. She thrives on danger, spectacle, and reinvention, but her role as a murderer adds a dark, unpredictable edge to her character. Rose is bold, chaotic, and unapologetically wild, but that persona masks a past filled with survival, loss, and emotional isolation. She has learned to trust no one and to rely only on herself.

Their worlds collide in a story that blends romance, violence, and psychological tension. What begins as a connection rooted in curiosity and shared darkness evolves into something far more consuming. The plot explores their growing bond as they navigate external threats, internal demons, and the dangerous consequences of their choices. The romance builds through tension, push and pull dynamics, and moments of vulnerability that feel hard-earned rather than easy.

Side storylines enrich the narrative, particularly those tied to the circus environment and the broader criminal elements surrounding Rose’s life. The Silveria Circus itself becomes a character of sorts, filled with intrigue, secrecy, and a sense of found family that contrasts with the brutality of Rose’s actions.

Highlights and Limitations

One of the strongest highlights of this audiobook is the complexity of its characters. Fionn and Rose are not softened for the sake of romance. Their flaws remain front and center, which makes their connection feel intense and believable. The contrast between Fionn’s controlled, almost clinical demeanor and Rose’s reckless, fiery nature creates a compelling dynamic that drives the story forward.

The romance is undeniably dark and charged with tension. The intimate scenes are explicit and emotionally loaded, leaning more toward intense and raw than soft or tender. The spice level is high, but it is not gratuitous. Instead, it reflects the characters personalities and their struggles with control, trust, and vulnerability.

I love that Rose uses her dark side to help women in trouble. Women that are in terrible situations who ask her for help. She is a murderer, but as Dexter Morgan showed us, there are some serial killers who are just vicious murderers who prey on the innocent and some that choose to use their darkness to rid the world of people who who live to hurt others. She is really doing the world a favor getting rid of those kinds of people.

Fionn is an odd character, and it was hard to figure him out. He seemed very quiet and unassuming. Though it was obvious that he had a history. He spends his spare time jogging and he does crochet, is even in a crochet circle with several of the older women in the community. He seems a bit naïve for someone with a brother who is a contract killer (Lachlan from Leather & Lark. We find out later that he does have a bit of a dark side that he has been hiding from.

The atmosphere is another standout element. The circus setting adds a unique, almost hypnotic backdrop that enhances the sense of danger and unpredictability. Combined with the darker themes of violence and morality, the story maintains a gripping tone throughout.

That said, the intensity of the characters and their actions may not appeal to everyone. Both Fionn and Rose operate in morally gray, often outright dark territory, which can make them difficult to fully root for. At times, the pacing can feel uneven, especially when balancing romance with the heavier plot elements. Some side storylines, while interesting, may feel underdeveloped compared to the central relationship.

Narration and Performance

Samantha Brentmoor and Eric Nolan deliver a strong duet performance that elevates the material. Brentmoor captures Rose’s boldness and unpredictability with precision. She brings out both the character’s fierce independence and the quieter, more vulnerable moments that reveal her inner struggles.

Eric Nolan’s portrayal of Fionn is equally compelling. His voice carries a calm, measured quality that fits the character’s controlled nature, but he also conveys the underlying tension and emotional depth that define Fionn’s arc. His performance adds nuance to a character who could otherwise come across as too distant. Though I wasn’t too fond of his Irish accent. He didn’t do a bad job; I just am not fond of accents.

Together, their performances create a believable chemistry that enhances the romance. The emotional beats land effectively, and the shifts between intensity and vulnerability feel natural. The narration helps balance the darker aspects of the story, making it immersive without becoming overwhelming.

My one criticism is that these same two narrators also did the last book Leather & Lark, and in a series where each book focuses on a different couple, I tend to like it better when there are different narrators for each book. Though that is just a little pet peeve of mine and not something that really bothers me very much.

Final Opinion

Scythe & Sparrow is a fitting conclusion to the trilogy, delivering a romance that is as dark and dangerous as it is compelling. It leans heavily into morally complex characters, emotional intensity, and a relationship that is anything but conventional.

Fionn and Rose are not easy characters to love, but that is precisely what makes their story engaging. Their connection feels earned through conflict, vulnerability, and a shared understanding of darkness. The high level of spice, layered with emotional weight, adds to the story rather than distracting from it.

While the book may not suit readers looking for lighter romance or clear-cut heroes, it will strongly appeal to those who enjoy dark romance with psychological depth and high stakes. Combined with excellent narration, this audiobook offers an intense and memorable listening experience that closes the trilogy on a powerful note.

Although I enjoyed the book, the massive hype on Bookstagram and BookTok set expectations it never fully met for me. I liked all three installments, but none of them crossed into “love” territory for me. Balancing humor with serial‑killer chaos is a tough needle to thread, and while this series handles it competently, I’ve seen it executed with sharper wit and more unhinged energy in other dark romances. Here, the characters dipped into “crazy” moments but spent most of their time feeling surprisingly normal, which softened the edge and often made me forget I was reading a dark romance at all.
