When Bora swaps bodies with a homicidal duchess, the sweet-tempered wallflower must embrace her inner villainess to survive and save her country.

Within an hour of Bora's arrival in Arahasnor, she runs into her toxic ex-boyfriend, offends a malicious noblewoman, and narrowly escapes from the city guards. Never the type for adventures—unlike her sister, Holy Maiden Ysabel, who left the family farm and scandalously eloped with Dark Lord Kaine—Bora intends to quickly return home and settle back into her usual role as the plain, boring sister. That is, until there's a freak magical accident.

Suddenly, Bora finds herself in the life—and body—of the Blood Duchess, a woman who once threatened to have her killed. Now a noblewoman in a kingdom on the verge of economic collapse, the citizenry hangs her in effigy, and her staff spits in her food. It's too much for a farm girl without a mean bone in her body to handle. Unfortunately, the previous ruler sold Arahasnor to three different foreign powers, and only their crippling fear of the Blood Duchess is holding them off...as long as Bora can successfully embody the ruthless villainess. At least she's not alone in this bizarre charade; she has the support of Countess Donya, her heroic celebrity crush.

And she'll need it. Because if Bora's real identity gets uncovered, she'll die. But after an assassin named Ari mistakenly targets her for revenge, she strikes a deal with him: she'll help find the actual duchess in exchange for his protection. As someone who struggles with body-image issues, Bora feels drawn to Ari's confidence, rakish charm, and gender queerness. But a love triangle may be a distraction she can't afford, especially when it turns out her sister is among the enemies coming to town to challenge the Blood Duchess.

After spending years obsessing over her weight, the death threats scare Bora less than showing off her extremely generous curves in the Blood Duchess's lowcut dresses. But if she can embrace the beauty of her new body, she might just learn to love her true self as well. Though, appearances will be irrelevant if the duchess's adversaries remove her head from her shoulders....
