A story about the cost of ambition, and what it means to protect love in a world built on power and secrecy.
What happens when love becomes all-consuming and destructive? A Traitorous Heart by Erin Cotter explores that question through court intrigue, secret societies, forbidden feelings, and an unhealthy hunger for power. A strong female protagonist ties it all together, though at times she seems less than adept at tying the laces.
The story is narrated by Jacqueline “Jac” d’Argenson-Aunis, a lady-in-waiting to Princess Marguerite “Margot” Valois, daughter of Catherine de Medici, in 1572 France. Raised by her uncle after her mother’s death in childbirth, Jac dreams of independence and of rising beyond her commoner’s birth. Those ambitions center on gaining entry to the highly secretive spy society known as Societas Solis, a goal that will cost her more than she anticipates, all while France teeters on the edge of religious war.
Cotter’s writing style is restrained, precise, and psychologically attuned, which makes it well suited to court intrigue. Her controlled sentences and carefully chosen metaphors allow tension to build between what is said and what is withheld. Prose that is highly observant of interpersonal dynamics mirrors the very setting she is writing about, a court full of gossip and secrets, where many wear two faces. She trusts her reader to read the room.
The main characters are well crafted, with clear strengths and vulnerabilities, as well as defined dreams and fears. Some of the more minor figures, such as Catherine de Medici, could have benefited from greater depth. The pacing felt off-kilter to me, seesawing between slow build and sudden bursts of action. The climax, in particular, seemed to arrive emotionally before it did narratively; it took too long to reach its peak, then rushed through its resolution. Jac does ultimately grow as a character, learning that love is fragile and must be handled with care in a world that is often unkind, though it felt like it took her ages to get there. She is, undeniably, a stubborn protagonist.
I enjoyed reading A Traitorous Heart, though there were several moments that required a level of suspended realism high enough to prompt a quiet chuckle. Perhaps I am simply too old and cynical, but certain events strained plausibility for a woman living in that century. Still, I appreciated what I took to be the novel’s overarching message. This is a good fit for older readers of the young adult genre, particularly given the book’s descriptive violence. Readers who enjoy historical fiction threaded with magical realism may also find much to admire here.
Nerd Rating: 🤓🤓🤓 — Smart, atmospheric court intrigue with thoughtful ideas and uneven execution.
