New York Times bestselling author and historian Javier Sierra delves into one of history’s greatest mysteries with his latest work, The Lady in Blue.

Sierra will sign his new book, Friday, July 6, 6-8 p.m., at Page & Palette, 32 S. Section St. in Fairhope.

Sierra believes in the idea that there are no coincidences in life.

In fact, he believes that it is his destiny to help shed light on some of the great mysteries of the world, and he does just that with his latest novel as he unearths answers to an enigma of the American Southwest and Spain.

The Lady in Blue is an entertaining whodunit infused with an intriguing real-life historical mystery: the Lady in Blue who magically appeared to Native Americans in the early 17th century.

An intriguing blend of spellbinding action, modern metaphysics and ancient religion and faith, The Lady in Blue explores the trances and bilocation (the power of being in two places at once) of María Jesús de Ágreda, a 17th century nun from Spain, who was accused by the Inquisition of traveling a distance of 6,000 miles more than 500 times to the New Mexican territories to propagate the word of God — without ever leaving her monastery.

Sierra uses literature as a vehicle to investigate some of the most puzzling mysteries of the past, meticulously researching them, and heightening their enigma in his quest to arrive at a probable solution to the questions they pose.
