Description
A deft and immersive psychological suspense debut about a luxury party planner who becomes obsessed with a woman she encounters in a hospital waiting room.
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.
