Perfect for you if...

  • You love historical fiction centred on real women navigating impossible political circumstances, not just watching from the sidelines.
  • You're drawn to stories about medieval power plays and court intrigue, especially when they involve the Welsh Marches and Edward II's reign.
  • You appreciate character-driven narratives where a woman's resilience and intelligence are the actual plot, not a subplot to a man's ambitions.

Maybe not for you if...

  • You prefer faster-paced plots with less political exposition and more action sequences.
  • You're looking for a romance where the relationship is the primary focus rather than the marriage being the entry point to larger historical events.
  • You struggle with historical fiction that requires you to track multiple nobles, alliances, and medieval legal complexities.

About this book

Set in the Welsh Marches in 1301, this novel follows Johane de Geneville, a strong-willed heiress married to Roger Mortimer, Earl of March, at age fifteen. Johane becomes entangled in treacherous court politics and dangerous secrets as her husband deposes Edward II and rules England alongside Queen Isabella. When Roger is accused of treason, Johane loses her freedom and must navigate catastrophic events while fighting for justice, with her life and her children's futures at stake. The novel explores whether she will be destroyed by her husband's mistakes or find a way to escape her circumstances.
