A queer historical fantasy/romance set in a version of 1899 New York City where magic is common and convenient, Coup de Coeur follows the journey of three men whose fates are tied to the seemingly sudden appearance of a strange, possibly sentient, grimoire.
Calix Addington, Earl of Batherton, has a complicated relationship with his friend and former classmate, Lawton Adler. Lawton's tendency to attract, and often cause, trouble leaves Calix sometimes holding the bag (which definitely happens). Calix is also harboring a secret - he's an Oracle, like his mother, and in a world where small magic is meant for aesthetics and convenience, larger displays of magic are frowned upon, sometimes illegal, and very much what the church and several important organizations fear.
When Calix is stuck with a strange book after Lawton's shady dealings go wrong one spring morning, he takes shelter in Ethaniel Harkness's magical tailoring shop. Calix and Ethaniel know each other as customer and tailor, but Ethaniel's kind heart won't let Calix stay in danger. As Calix hears the strange book speak in his mind, Ethaniel contacts his old flame Aubrey Lavigne. Aubrey's expertise with magical objects as the curator for the Magnificus Collectio, an archive hidden behind a tourist trap museum, will be key to understanding what this book truly is.
Magic, love, lust, fear, and danger run rampant as this strange book becomes the catalyst for a much larger plot conducted by a secret sect known as The Golden Order. With The Golden Order giving chase to retrieve the book, Calix, Ethaniel, and Aubrey's lives tangle and they must flee the city to separate Calix from the book, shake off their pursuers, and find time for their burgeoning attractions.
Coup de Coeur has deep roots in the real-life queer history of New York City, but also in art and culture.
