Vincent, having grown up as the privileged daughter of artists, has a lovely life in many ways. At forty-four, she enjoys strolling the streets of Paris and teaching at the modern art museum; she has a vibrant group of friends; and she's even caught the eye of a young, charismatic man named Loup. But Vincent is also in Paris to escape a painful betrayal: her husband, Cillian, has published a bestselling book divulging secrets about their marriage and his own past, hinting that when he was a teenager, he may have had a child with a young woman back in Dublin-before he moved to California and never returned.
Now estranged from her husband, Vincent has agreed to see Cillian again at their son's wedding the following summer, but Loup introduces new complications. Soon they begin an intense affair, and somewhere between dinners made together, cigarettes smoked in the moonlight, hazy evenings in nightclubs, and long, starry walks along the Seine, Vincent feels herself loosening and blossoming.
In a journey that is both transportive and intimate, Half-Blown Rose traverses Paris, art, travel, liminal spaces, and the messy complexities of relationships and romance, with excerpts from Cillian's novel, playlists, and journal entries woven throughout. As Cillian does all he can to win her back, Vincent must decide what she wants . . . and who she will be.
