Many of the stories feature Catherine LeVendeur, the beloved protagonist of ten of Newman’s novels, and Solomon, Catherine’s Jewish merchant cousin. These stories takes us into the day to day reality of medieval religious and family life, as it is lived by a variety of people: from nuns, noble people, scholars, courtiers, merchants, hermetic spinsters and children. Fans of the novels will find this collection delightful as the author explains the origins of these stories and the evolution of her protagonists in the novels; these tales also serve as a great introduction to her work for newcomers.

Book excerpt: “The reigning queen of historical fiction” -- Fiona Davis, New York Times bestselling author of The Lions of Fifth Avenue The New York Times and USA Today bestselling author of The Huntress and The Alice Network returns with another heart-stopping World War II story of three female code breakers at Bletchley Park and the spy they must root out after the war is over. 1940. As England prepares to fight the Nazis, three very different women answer the call to mysterious country estate Bletchley Park, where the best minds in Britain train to break German military codes. Vivacious debutante Osla is the girl who has everything—beauty, wealth, and the dashing Prince Philip of Greece sending her roses—but she burns to prove herself as more than a society girl, and puts her fluent German to use as a translator of decoded enemy secrets. Imperious self-made Mab, product of east-end London poverty, works the legendary codebreaking machines as she conceals old wounds and looks for a socially advantageous husband. Both Osla and Mab are quick to see the potential in local village spinster Beth, whose shyness conceals a brilliant facility with puzzles, and soon Beth spreads her wings as one of the Park’s few female cryptanalysts. But war, loss, and the impossible pressure of secrecy will tear the three apart. 1947. As the royal wedding of Princess Elizabeth and Prince Philip whips post-war Britain into a fever, three friends-turned-enemies are reunited by a mysterious encrypted letter--the key to which lies buried in the long-ago betrayal that destroyed their friendship and left one of them confined to an asylum. A mysterious traitor has emerged from the shadows of their Bletchley Park past, and now Osla, Mab, and Beth must resurrect their old alliance and crack one last code together. But each petal they remove from the rose code brings danger--and their true enemy--closer...

Download or read book Foreign Gods Inc written by Okey Ndibe and published by Soho Press. This book was released on 2014-01-14 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a disciple of the late Chinua Achebe comes a masterful and universally acclaimed novel that is at once a taut, literary thriller and an indictment of greed’s power to subsume all things, including the sacred. Foreign Gods, Inc., tells the story of Ike, a New York-based Nigerian cab driver who sets out to steal the statue of an ancient war deity from his home village and sell it to a New York gallery. Ike's plan is fueled by desperation. Despite a degree in economics from a major American college, his strong accent has barred him from the corporate world. Forced to eke out a living as a cab driver, he is unable to manage the emotional and material needs of a temperamental African American bride and a widowed mother demanding financial support. When he turns to gambling, his mounting losses compound his woes. And so he travels back to Nigeria to steal the statue, where he has to deal with old friends, family, and a mounting conflict between those in the village who worship the deity, and those who practice Christianity. A meditation on the dreams, promises and frustrations of the immigrant life in America; the nature and impact of religious conflicts; an examination of the ways in which modern culture creates or heightens infatuation with the "exotic," including the desire to own strange objects and hanker after ineffable illusions; and an exploration of the shifting nature of memory, Foreign Gods is a brilliant work of fiction that illuminates our globally interconnected world like no other.
