Dark Eyes, Lady Blue tells the story of Sister María of Ágreda's remarkable life. Maria was born in Agreda, Spain, in 1602, and vowed there as a nun at age seventeen. From birth to her death in 1665, she never left the small town. Yet her accomplishments had a lasting impact in Spain and as far away as the American Southwest, where she is celebrated to this day.

Although cloistered in Agreda's Monastery of the Immaculate Conception, Maria grew to be a renowned mystic, a widely read author, and an advisor to the King of Spain. She experienced religious ecstasy that inspired her visionary writings and - quite remarkably - communications with the Jumano Indians of what would later become the states of Texas and New Mexico. When Spanish missionaries met the Jumano Indians, their chief expressed a desire to be baptized because of the supernatural visits from the mystical ""lady in blue.""

This fresh telling of Maria's story is one that will appeal to readers young and old and provides an unforgettable perspective on early American exploration of Texas and New Mexico.
