A Traitorous Heart by Erin Cotter tells the tale of a noblewoman in the scandalous French court who finds herself under the dangerous and watchful eye of the Parisian royalty. She falls in love with the handsome king, who is betrothed to her former lover, in this bisexual reinterpretation of The Three Musketeers by way of Bridgerton and F.T. Lukens.

Paris, 1572. Seventeen-year-old Jacqueline β€œJac” d’Argenson-Aunis is a lady-in-waiting to her best friend and former lover, the French Princess Marguerite β€œMargot” de Valois. However, she dreams of more. If Jac plays her cards right, she hopes to become a full member of the Societas Solis, a secret society of spiesβ€”just like her uncle and guardian, Viscount Gabriel d’Argenson-Aunis.

But it’s hard to focus on her own ambitions while France is on the brink of war. The only thing that might save the country is an allianceβ€”a marriage between the Catholic Princess Margot and Henry, the awful son of the Huguenot queen. Who would be the perfect person to play matchmaker? Jac, of course.

Jac resents lying to her best friend almost as much as she resents the brazen and arrogant King Henry, but it’s her one chance to prove to the Societas Solis that she belongs among their ranks before her uncle can marry her off or worse. The more time Jac spends in the clandestine corners of the French Court, she starts to wonder if Henry is…not as terrible as she once believed. And the Societas Solis may not be what they seem.

Politics. Spies. Chaos in the French court. Perhaps even witchcraft? Everything’s more dangerous when love is involved.
