A sweeping, richly detailed portrait of Isabella of Castile — the passionate, determined woman who became one of history’s most powerful queens.
 
In The Queen’s Vow, C. W. Gortner, master of historical fiction, vividly reimagines the life of one of
Europe’s most fascinating monarchs. Set against the tumultuous backdrop of 15th-century Spain, the novel brings to life the courtly intrigues, political alliances, and religious turmoil that defined Isabella’s reign.
 
Before she was known as the Catholic Queen who united Spain, Isabella of Castile was a young princess fighting for her life and her throne. Torn between duty, faith, and love, Isabella’s journey from sheltered girl to visionary ruler is marked by courage, betrayal, and destiny. From her turbulent marriage to Ferdinand of Aragon to her bold decision to finance Columbus’s voyage, Isabella’s story unfolds as one of ambition, conviction, and transformation.
 
Told in Isabella’s own voice, the story reveals not just the queen who shaped empires, but the woman behind the crown — driven by faith, torn by love, and challenged by the demands of power.
