Perfect for you if...
- You love psychological thrillers where the protagonist isn't entirely sympathetic and nothing is quite as it seems.
- You've read other McFadden books and want that same propulsive, twist-heavy storytelling with unreliable narrators.
- You enjoy domestic suspense where ordinary people's lives implode under pressure and surveillance.
Maybe not for you if...
- You prefer cosy mysteries or lighter thrillers where the stakes feel lower and the tone is less dark.
- You need to fully root for your protagonists. April is flawed and complicit in ways that might frustrate you.
- You're looking for a standalone that wraps up neatly. McFadden's endings often leave moral questions deliberately unresolved.
