The Queen’s Witness

A single intercepted letter turns a country girl into the most dangerous witness in Castile. Blanca Vergara arrives at the itinerant court of 1506 to restore her family's fortunes, and instead finds a widowed queen whom the kingdom has already agreed to call mad. Juana Estrada is grieving, brilliant, and entirely sane — and her own father wants her crown. Standing with the queen may cost Blanca her family, her love, and her liberty.
