Book Review: This Girl’s a Killer by Emma C. Wells

Do you just love watching bad things happen to bad dudes? The big guys like Harvey Weinstein, Louis C.K., Aziz Ansari, Andrew M. Cuomo, (and hopefully someday Donald Trump) are toppled publicly for all to see. But what about the everyday bad guys—the nobodies who use and abuse those who don’t have the power or the platforms to make their voices heard? In This Girl’s a Killer, Emma C. Wells introduces readers to Cordelia Black, a pharmaceutical rep by day and an unapologetic dispenser of justice by night. Set against the sultry, morally gray backdrop of South Louisiana, the novel delivers a character-driven thriller that’s as sharp and polished as its protagonist’s designer wardrobe.

Cordelia Black isn’t your typical serial killer. Or, as she would vehemently argue, she’s not a serial killer at all. To her, “Karma” isn’t just a concept; it’s her calling. Her targets are meticulously chosen—men who have evaded justice for their heinous crimes. And though the evening news might paint her as a monster, Cordelia’s actions feel like a balm for those who crave retribution in an unjust world.

Cordelia’s character arc is one of the novel’s most masterful elements. From the start, she exudes control and perfection—the kind of woman who’s as deliberate in her choice of victims as she is in her business deals. Yet as the story progresses, cracks appear in her carefully constructed facade. When her best friend begins dating a man who raises Cordelia’s suspicions, her internal conflict takes center stage. Is he truly a monster, or is Cordelia projecting her distrust of men? The stakes rise, and with them, Cordelia’s evolution from a calculated dispenser of justice to someone grappling with the moral complexities of her choices.

This journey of self-awareness and growth is what sets Cordelia apart from the archetype of the cold-blooded killer. She becomes more herself with each trial, and by the end, she’s not just an Agent of Karma; she’s a woman who’s learned what it means to bear the weight of her decisions.

What could have easily devolved into gratuitous gore is instead a tightly woven plot that balances tension, wit, and heart. Wells avoids the pitfall of shock value, opting instead for deliberate, meaningful storytelling. Every twist serves a purpose, and the pacing keeps readers hooked without sacrificing depth.

Beyond its gripping narrative, This Girl’s a Killer weaves in a potent line of social commentary. Wells deftly explores themes of patriarchy and systemic injustice. Through Cordelia’s eyes, readers confront the uncomfortable truth that even the most morally reprehensible men often escape punishment. Meanwhile, a woman daring to take justice into her own hands faces consequences far harsher than the crimes of her targets. It’s a pointed critique of a society that simultaneously idolizes and vilifies women who step outside the bounds of traditional morality.

This Girl’s a Killer is a dazzlingly sharp thriller that feels both timely and timeless. Cordelia Black is a protagonist who’s impossible to forget, and Emma C. Wells crafts her story with a precision that mirrors her heroine’s own calculated methods. For readers who revel in character-driven stories with a bite of social justice—or for those who secretly cheer when the bad guys get what they deserve—this book is an absolute must-read.

I couldn’t help but see shades of my own work in this story. Like Cordelia, I also enjoy doing bad things to bad men in my novels. However, in my case, the bad men are the protagonists in their own stories. In One Bad Cat and It Had to Happen, the male main characters take center stage as they fumble through life, each of them surprised when they find themselves in the position of having to face the consequences of their own bad actions. But perhaps that’s why This Girl’s a Killer resonated with me so deeply. It’s not just a story about a killer; it’s a story about a woman reclaiming agency in a world determined to strip it away.

I loved This Girl’s a Killer so much, I decided to start a GoodReads list of similar novels. Check it out and feel free to add your favorites that fit the description!
