Book Description
Pearl's Secret is a remarkable autobiography and family story that combines elements of history, investigative reporting, and personal narrative in a riveting, true-to-life mystery. In it, Neil Henry—a black professor of journalism and former award-winning correspondent for the Washington Post—sets out to piece together the murky details of his family's past. His search for the white branch of his family becomes a deeply personal odyssey, one in which Henry deploys all of his journalistic skills to uncover the paper trail that leads to blood relations who have lived for more than a century on the opposite side of the color line. At the same time Henry gives a powerful and vivid account of his black family's rise to success over the twentieth century. Throughout the course of this gripping story the author reflects on the part that racism and racial ignorance have played in his daily life—from his boyhood in largely white Seattle to his current role as a parent and educator in California. The contemporary debate over the significance of Thomas Jefferson's longtime romantic relationship with his slave, Sally Hemings, and recent DNA evidence that points to his role as the father of black descendants, have revealed the importance and volatility of the issue of dual-race legacies in American society. As Henry uncovers the dramatic history of his great-great-grandfather—a white English immigrant who fought as a Confederate officer in the Civil War, found success during Reconstruction as a Louisiana plantation owner, and enjoyed a long love affair with Henry's great-great-grandmother, a freed black slave—he grapples with an unsettling ambivalence about what he is trying to do. His straightforward, honest voice conveys both the pain and the exhilaration that his revelations bring him about himself, his family, and our society. In the book's stunning climax, the author finally meets his white kin, hears their own remarkable story of survival in America, and discovers a great deal about both the sting of racial prejudice as it is woven into the fabric of the nation, and his own proud identity as a teacher, father, and black American.

Book Description
WHEN LUCIE MONTGOMERY FINDS the body of prominent wine merchant Paul Noble hanging from a beam in his art studio not far from her Virginia vineyard, she is unwittingly dragged into Noble’s murky past. Once a member of the secretive Mandrake Society, Noble might have aided in a cover-up of the deaths forty years ago of a disabled man and a beautiful young biochemist involved in classified government research. A seemingly innocent favor for an old friend of her French grandfather sends Lucie to California, where she teams up with Quinn Santori, who walked out of Lucie’s life months earlier. Soon Lucie and Quinn are embroiled in a deadly cat-and-mouse game that takes them from glittering San Francisco to the legendary vineyards of Napa and Sonoma, and back home to Virginia, as they try to discover whether a killer may be seeking vengeance for the long-ago deaths. As Lucie and Quinn struggle to uncover the past, they must also decide whether they have a future together. Blending an intriguing mystery with an absorbing plot, vivid characters, and a richly evoked setting, The Sauvignon Secret should be savored like a glass of fine wine.

Book Description
In Securing VoIP Networks, two leading experts systematically review the security risks and vulnerabilities associated with VoIP networks and offer proven, detailed recommendations for securing them. Drawing on case studies from their own fieldwork, the authors address VoIP security from the perspective of real-world network implementers, managers, and security specialists. The authors identify key threats to VoIP networks, including eavesdropping, unauthorized access, denial of service, masquerading, and fraud; and review vulnerabilities in protocol design, network architecture, software, and system configuration that place networks at risk. They discuss the advantages and tradeoffs associated with protection mechanisms built into SIP, SRTP, and other VoIP protocols; and review key management solutions such as MIKEY and ZRTP. Next, they present a complete security framework for enterprise VoIP networks, and provide detailed architectural guidance for both service providers and enterprise users. 1 Introduction 2 VoIP Architectures and Protocols 3 Threats and Attacks 4 VoIP Vulnerabilites 5 Signaling Protection Mechanisms 6 Media Protection Mechanisms 7 Key Management Mechanisms 8 VoIP and Network Security Controls 9 A Security Framework for Enterprise VoIP Networks 10 Provider Architectures and Security 11 Enterprise Architectures and Security
