GOOD INTENTIONS

St. Martin’s Press, February 2026
Cady has worked hard to have a good life. She has a thriving luxury event-planning business, the man she’s loved since she was seventeen, and a social calendar she can barely keep up with. She also has Dana, her identical twin, her beyond best friend, her most trusted confidante. When Cady gets a call that Dana has been in a serious accident and arrives moments too late to say goodbye, her world falls apart.
But to Cady’s family’s growing concern and confusion, it’s not Dana’s death that consumes her. It’s Morgan, a grieving mother Cady encountered in the hospital waiting room, the day her sister died. It can’t be a coincidence, that they both experienced tragedy at the same moment, in the same place―Cady doesn’t believe in coincidences. Instead, she is convinced that she must help this stranger overcome her tragedy, in order to come to terms with her own.
Or…is there more to it? Is it possible that Cady wants something else from Morgan? Something she can’t even admit to herself?
Slyly twisted and deeply provocative, GOOD INTENTIONS captures the moral ambiguity that can arise in the face of impossible choices. Like the aftermath of a car accident―and against your better judgment―you won’t be able to look away.

Olivia Branch has a legendary palette—or, rather, had. She was a master sommelier—a distinction given to only 269 people in the world, and only a handful of them women–with a mental catalogue for the scent and taste of wines that ran into the thousands. She was even, for a time, the youngest-ever Head Sommelier at the most prestigious French restaurant in New York City. That is, until Covid robbed her of one of her greatest weapons: her sense of taste.
