A work of queer historical fiction, A Traitorous Heart follows scandal-born Jacqueline “Jac” d’Argenson-Aunis as she navigates the treacherous politics of the French court at a time when it seems that one wrong move could push France into war. As if that weren’t daunting enough, Jac yearns to join the Societas Solis, a secret society of spies that her uncle – the sole family member she has and the man who raised her – is part of. The Societas Solis is shrouded in mystery and secrecy, but Jac knows how to keep secrets, weave compelling lies founded on scraps of truth, and fight and wield weapons. Except that when her uncle finally relents and allows Jac to take a small part in Societas Solis work, her first mission is nothing like what she expected: she is to play royal matchmaker for her best friend and former lover, the princess of France, and the King of Navarre. With countries and hearts on the line, what could go wrong? (Spoiler: a lot.) What starts out as political matchmaking spirals and snowballs: assassins and murders, exhumations, impossible promises, improbable romance, betrayal, madness, and a dash of magic.
A Traitorous Heart brims with complex characters grappling with society’s expectations and their own desires. Jac, Henry, and Margo all have big, unruly emotions and complicated relationships with themselves, others, and their countries. (Jac’s relationship with her uncle stuck out to me in particular for its well thought-out complexity, nuance, and evolution.) These characters are real and messy, making mistakes, getting upset, doubting themselves, pushing themselves. Jac’s journey throughout the book is nothing short of transformative and revelatory: a lonely girl becomes a confident woman learning to put her trust in others and their unconditional love for her, instead of carrying her burdens alone and unacknowledged. Jac’s deep-seated need to prove herself is something that I – and I imagine many people, women in particular – relate to. I loved watching her acknowledge and accept her own self-worth (and be a skilled, accomplished badass who can take care of herself!).
Cotter’s beautiful writing abounds with gorgeous figurative language (including recurring imagery for specific characters that highlights and supports their arcs and relationship dynamics), laugh-out-loud witticisms, and heart-rending moments. The romance is only one part of the plot and doesn’t overwhelm the narrative. Rather, it compliments the non-romantic plot threads, adding to the story’s existing stakes and tension. On top of her deft storytelling, compelling characters, and nuanced plot, Cotter also does a small thing that I personally love when authors do: there is a line in the book which includes, and contextualizes, the title of A Traitorous Heart. It’s in the latter half of the book but well worth the wait!
A Traitorous Heart is a captivating, well-written take on historical fiction that I didn’t want to put down (while simultaneously not wanting it to end…). More than that, it is exactly the kind of book I wish I’d had growing up, and I’m grateful that it exists for people of all ages now. I simply adore it! Read it and discover Cotter’s brilliance! (And while you’re at it, grab her debut novel, By Any Other Name, too!)
Many heartfelt thanks to the author and the publisher for the eARC!
