     “(Hynd is)…a few notches above the Ludlums and Clancys of the world." - Booklist. 'Eisenhower’s Spy' is Noel Hynd’s tough hard-hitting sequel to 'Truman’s Spy'. It is a major new work of action and espionage from the author of 'Flowers From Berlin' and 'Return to Berlin.' It is the summer of 1958. President Dwight D. Eisenhower personally enlists F.B.I. Special Agent Thomas Buchanan (the central character of Hynd’s 'Truman’s Spy') for a top secret assignment independent of the FBI and CIA. The President asks Buchanan to oversee the investigation of a perplexing murder in broad daylight in Manhattan. The best detectives in New York City cannot pull the case together. Or maybe they don’t want to. Was the homicide a random slaying, a gangland ‘hit,’ a drug deal gone wrong or a political assassination? And the further question: why is this homicide, which might otherwise be a state or city investigation, the focus of such close White House attention? Within days of starting his investigation, Buchanan finds himself, his life, his career and the woman he loves in jeopardy. He navigates a lethal web of Russian spies, local hoodlums, political provocateurs from the left and the right, the CIA, rival agents in the FBI, surly New York cops and Caribbean revolutionaries. The case is a nightmare, as are its ramifications. Equally perilous are the gritty gang-controlled urban streets where Buchanan must go to seek answers. Buchanan soon finds himself working with an unpredictable New York City police lieutenant named Paul Maguire. A beautiful but suspicious young woman named Laura Brookfield filters in and out of the case. Day to day, Laura either aids them or sabotages them. And yet, she may be the key to Buchanan's investigation. The story twists and turns from New York to Washington to Havana and back again. The case comes in and out of focus like a mirage on a broiling summer afternoon. Buchanan moves from the drug dens of upper Manhattan to the mob nightclubs of midtown to the edgy coffee houses of Greenwich Village. He visits the hot jazz joints of the West Fifties and the corrupt police precincts of the pre-Serpico era. Questions are many. Answers are few. Buchanan must make his own good luck. Meanwhile, the President is waiting for a report. To some, America of the 1950’s was a bright, optimistic and prosperous place. But in 'Eisenhower’s Spy' a deeper reality smolders beneath the surface. The decade had begun with two wars: a bloody conflict in Korea that stalemated in 1953 and a global cold war that would intensify through the decade. Berlin, Budapest and Taiwan were flashpoints of conflict and potential sparks for another world war. Americans passed the decade in fear of Soviet subversion from within or a sudden Soviet nuclear attack from afar. Worse, revolutionary ferment was as close as ninety miles south of Florida as Fidel Castro’s revolutionary army crept increasingly closer to mobbed-up Havana. 'Eisenhower’s Spy' is a spy story that buzzes with the energy of numerous intrigues, love affairs, memorable characters, remorseless criminality and quirks of fate set across a dark set of years in the middle of the Twentieth Century. 'Eisenhower’s Spy' will underscore the critics’ lofty assessment of Noel Hynd’s unique way with a tough hard-hitting spy novel: a full cast of memorable people, romance, uncompromising historical accuracy and heart pounding suspense. The millions of readers of Noel Hynd’s previous novels will not be disappointed.

    After participating in the special promotion, Dante finds himself thrust into the hidden world of the Spiritual Warriors, a group of men and women, fighters with special abilities who are trained and dedicated to keeping this plane of existence safe from evil. He discovers that a war has been raging between the Warriors, those sworn to protect this plane of existence from destruction and the Shadows, those who would see it enslaved under the rule of evil. The Ascendants-Book 2 Ascendants are being killed and the barrier between worlds is failing. Dante, along with a group of Warriors and Guardians must confront the Harbinger. An undying servant of Lucius, a killer who can’t die. His purpose is to destroy the barriers and recapture Maelstrom-a sentient weapon of evil created by his master and wielded by Dante. Can Dante learn how to control Maelstrom before the evil corrupts and kills him? Can the Warriors of the Way stop the Harbinger, and prevent the fall of the barriers before it's too late? Or will Lucius escape and kill them all? The Fallen Warrior-Book 3 In a nearly fatal ritual, the shadow of Lucius has seared Dante, stripping him of Maelstrom and cutting him off from his chi. Dante, now a fallen warrior must find a way to undo the searing using only his skill and training to face those who want him dead. There are rumors of another weapon. A weapon powerful enough to stand against Maelstrom and Lucius.To find this weapon, Sylk will have to follow the trail of the Mikai back to the Warriors of the Way. Someone is forcing them to kidnap and eliminate the Rah Ven. Someone powerful enough to strike fear in the hearts of the Mikai and control the Black Lotus, who have designated Meja rogue and a traitor, a crime punishable by death. Can Dante undo the searing in time to face Lucius and Maelstrom? Will Sylk find the path to the weapon, discovering who controls the Mikai and the Black Lotus? Will Meja prove her innocence, or fail and be killed? The Warrior Ascendant-Book 4 The Wheel has unleashed the Kriyas. Creatures of fearsome power that devour life-force. They have been set on a path to destroy anyone who stands in the way of recovering the three foci, weapons of immense power. Dante, having undone the searing must now locate the third foci, Shadowstrike, the only weapon powerful enough to stand against Maelstrom and Lucius. From his prison in the forgotten plane, Lucius now with the power of Maelstrom has been patiently restoring the connection to the Nexus. One more weapon will complete the bridge. Once restored every plane will be in danger of destruction. Dante, together with Sylk and Meja, return to the Akashic Records. There they will seek to uncover the identity of The Wheel. Will they find Shadowstrike, stop the Kriyas, and prevent Lucius from escaping? The Master Warrior-Book 5 Dante has bonded to Shadowstrike. There is only one problem, the weapon is slowly killing him. The Wheel reveals his plan for dominion and destruction of the planes. In order to face this threat, Dante faces his hardest decision as a warrior. Will he sacrifice his life so that others may live or will he fight for survival? The Warriors of the Way is an action filled mix of martial arts, magic and mayhem.

    Python is considered easy to learn, but there's no quicker way to mastery of the language than learning from an expert teacher. This edition of "Learning Python" puts you in the hands of two expert teachers, Mark Lutz and David Ascher, whose friendly, well-structured prose has guided many a programmer to proficiency with the language. "Learning Python," Second Edition, offers programmers a comprehensive learning tool for Python and object-oriented programming. Thoroughly updated for the numerous language and class presentation changes that have taken place since the release of the first edition in 1999, this guide introduces the basic elements of the latest release of Python 2.3 and covers new features, such as list comprehensions, nested scopes, and iterators/generators. Beyond language features, this edition of "Learning Python" also includes new context for less-experienced programmers, including fresh overviews of object-oriented programming and dynamic typing, new discussions of program launch and configuration options, new coverage of documentation sources, and more. There are also new use cases throughout to make the application of language features more concrete. The first part of "Learning Python" gives programmers all the information they'll need to understand and construct programs in the Python language, including types, operators, statements, classes, functions, modules and exceptions. The authors then present more advanced material, showing how Python performs common tasks by offering real applications and the libraries available for those applications. Each chapter ends with a series of exercises that will test your Python skills and measure your understanding."Learning Python," Second Edition is a self-paced book that allows readers to focus on the core Python language in depth. As you work through the book, you'll gain a deep and complete understanding of the Python language that will help you to understand the larger application-level examples that you'll encounter on your own. If you're interested in learning Python--and want to do so quickly and efficiently--then "Learning Python," Second Edition is your best choice.
