Sarah MacLean didn't just write a book when she released Nine Rules to Break When Romancing a Rake back in 2010. She basically threw a brick through the window of the "polite" Regency romance genre. If you’ve spent any time lurking in the historical romance community or scrolling through "BookTok" lately, you know that this specific title is often cited as the gateway drug for an entire generation of readers. It’s the book that turned the trope of the "wallflower" on its head by giving her a list, a loud personality, and a very scandalous set of goals.
Honestly, the Regency era in fiction can sometimes feel a bit stiff. We’re used to the tea parties and the subtle glances across a ballroom. But MacLean’s debut in the Love By Numbers series felt different. It was loud. It was sweaty. It was unapologetically feminist in a setting that usually restricts women to embroidery and husband-hunting. When we talk about the nine rules to break when romancing a rake, we’re talking about a narrative shift where the heroine, Lady Calpurnia Hartwell, decides she’s done waiting for a life that isn't coming.
The Cultural Impact of Callie’s List
Why does this book still rank so high on "Best Of" lists over a decade later? It's the relatability. Callie is twenty-eight—an "ancient" spinster by 1813 standards. Most of us have felt that specific sting of being overlooked or feeling like life is passing us by while we follow the rules. Callie’s decision to create a list of "manly" sins to commit isn't just a plot device; it’s a manifesto.
The rules she decides to break include things that seem trivial to us now but were social suicide back then. Fencing. Drinking scotch in a club. Smoking a cheroot. Riding astride. It’s about bodily autonomy and the right to experience the world. When she approaches the infamous Marquess of Ralston to help her navigate these sins, the chemistry isn't just about physical attraction—it's about a woman finally asking for what she wants.
MacLean, who has a background in education and is a vocal advocate for the romance genre as a site of political and social resistance, baked a lot of nuance into this story. She didn’t just write a "smutty" book; she wrote a book about the cost of reputation and the value of self-worth.
Breaking the Stigma of the "Spinster"
In historical romance, the "spinster" was often a tragic figure or a comedic foil until authors like MacLean, Lisa Kleypas, and Julia Quinn started reclaiming the term. In Nine Rules to Break When Romancing a Rake, Callie’s status as a spinster is her superpower. Because she is already "ruined" in the eyes of the ton—not by scandal, but by age—she has nothing left to lose.
This creates a fascinating dynamic with Gabriel St. John, the Marquess of Ralston. He’s the quintessential rake: cynical, bored, and devastatingly handsome. But he’s also a man who lives by a very different set of rules, mostly governed by his need to protect his sister’s reputation. The irony? The "perfect" rake is actually more trapped by social conventions than the "invisible" spinster.

Why Readers Keep Coming Back to the "Love By Numbers" Series
Romance novels live and die by their emotional beats. You can have all the fencing lessons and carriage rides you want, but if the internal growth isn't there, the book fails. MacLean excels at the "internal monologue of longing."
- The Fencing Scene: This is a fan favorite for a reason. It’s the first time Callie realizes she can be physically capable and competitive. It’s also where Ralston realizes she isn't just a "proper lady" he’s helping out of pity.
- The Scotch and Cheroots: There’s something inherently rebellious about a woman entering a male-only space. It’s a recurring theme in MacLean’s work (see her Hell’s Belles series for more of this).
- The Midnight Meetings: The stakes are high. If Callie is caught, she doesn't just lose her marriage prospects; she loses her family’s standing. Yet, the thrill of the risk is what makes her feel alive.
It's kinda wild how a book written in the late 2000s captures the vibe of 1800s London while feeling entirely modern. The dialogue is snappy. It doesn't get bogged down in "thee" and "thou" or overly formal prose that can make historicals feel like a chore to read.
The "Rake" Archetype: What MacLean Gets Right
The rake is a staple of the genre, but he can be a hard character to pull off without making him a jerk. Ralston works because his "rakishness" is a mask for his responsibilities. He isn't just out there breaking hearts for fun; he’s navigating a world where he has to be the protector of a legacy he didn't necessarily ask for.
When Callie enters his life with her list of nine rules to break when romancing a rake, she disrupts his controlled chaos. He’s used to women who want his title or his money. Callie just wants him to teach her how to fire a pistol. That shift in power—where the woman is the seeker of experience and the man is the facilitator—is what makes the romance feel balanced.

Real-World Context: The Regency Era Reality
It’s worth noting that the "rules" Callie breaks were very real. According to historians like Hannah Greig (who worked on The Favourite and Bridgerton), the social season was a brutal marketplace. A woman’s reputation was her only currency.
- Public Appearance: A lady could not be seen in a carriage with a man who wasn't a relative.
- The Waltz: Even the dance itself was considered scandalous when it first arrived in London because of the close physical contact.
- Astride Riding: Women rode side-saddle not just for modesty, but because riding astride was thought to be "unfeminine" and potentially damaging to their "virtue."
MacLean uses these historical anchors to make Callie’s rebellion feel earned. When she finally breaks the "big" rules—the ones involving intimacy and emotional vulnerability—it feels like a massive victory because we’ve seen her conquer the smaller social hurdles first.
How to Approach the Book Today
If you’re picking up Nine Rules to Break When Romancing a Rake for the first time, or if you're revisiting it after a decade, pay attention to the sisterhood. The relationship between Callie and her sister, Mariana, is the heartbeat of the book. Mariana is the "beautiful" one, the one the world was built for, yet she is Callie’s biggest cheerleader.
This subversion of the "jealous sisters" trope is a MacLean staple. She refuses to pit women against each other for the sake of a man's attention. Instead, the conflict comes from the world they live in and the internal barriers they have to break down.

Actionable Insights for Romance Readers
If you loved the themes in this book, here is how you can dive deeper into the genre or apply the "Callie Mindset" to your own reading:
- Look for "Wallflower" Tropes: If you liked Callie, check out The Wallflowers series by Lisa Kleypas. It explores similar themes of overlooked women finding their power.
- Follow the Author’s Podcast: Sarah MacLean co-hosts Fated Mates, a podcast that analyzes romance novels through a critical, feminist lens. It’s a great way to understand the "why" behind the tropes.
- Explore the Sub-Genre: If the "list" aspect appealed to you, look for "Growth and Agency" tags in romance databases. These books focus on the heroine’s personal development as much as the romance.
- Trace the Series: Don’t stop at Callie. The Love By Numbers series continues with Ten Ways to Be Adored When Landing a Lord and Eleven Scandals to Start to Win a Duke's Heart. Each book plays with the "numbers" and "rules" theme in a different way.
The enduring popularity of Nine Rules to Break When Romancing a Rake proves that we don't just want to read about perfect people in perfect ballrooms. We want to read about the people who feel a little out of place, who have a list of things they've always wanted to do, and who are brave enough to ask a rake for a light.
To fully appreciate the evolution of the genre, compare this 2010 release to MacLean's later works like Bombshell. You'll see a clear line from Callie's first tentative steps toward rebellion to the full-blown revolutionary heroines of the 2020s. The rules might change, but the desire to break them remains the same.
