NEW YORK TIMES BESTSELLER Leadership isn’t about a job title – it’s about action and behavior. In SPARK, entrepreneurs, business consultants and military Veterans Angie Morgan, Courtney Lynch, and Sean Lynch show how anyone can become an extraordinary leader by embracing seven key behaviors. Many people believe that leaders are the rare few at the upper echelons of a business or other enterprise. But the truth is leaders can be found at any level of an organization. These are the Sparks – the doers, thinkers, innovators, and key influencers who are catalysts for personal and organizational change. Sparks aren’t defined by the place they hold on an organizational chart. They are defined by their actions, commitment, and will. When Sparks are ignited, their actions can shape their future. They make things better. They’re the individuals who have the courage to challenge the status quo and take action. Frederick W. Smith, Chairman & CEO of FedEx Corporation, adds: The concept of leadership is not a difficult one to understand. It’s that straight-forward, but it’s by no means intuitive. It must be learned and practiced. SPARK will help you do just that. SPARK’s insights were hard-earned by its authors, Angie Morgan (Marine Corps), Courtney Lynch (Marine Corps), and Sean Lynch (Air Force), who today are sought-after consultants and keynote speakers, through their firm Lead Star, due to the relevant, engaging way they help individuals reimagine themselves as leaders so they can reach their true potential. Not only does SPARK provide you with the encouragement and motivation to be a leader, it also offers online resources that will further support your leadership development. With SPARK as a blueprint, anyone can become a catalyst for change, and any organization can identify and develop Sparks.

THE MOST DANGEROUS ASSASSIN IS THE ONE WHO BELIEVES HE IS ALREADY DEAD. A razor-sharp, high-tech, wildly imaginative new novel from internationally bestselling author John Twelve Hawks, Spark features a narrator unlike any in recent fiction—a man whose view of life and death is different from anything you’ve ever imagined. Jacob Underwood is a contract employee of the Special Services Section, a small shadow department buried within the multinational corporation DBG, headquartered in New York City. Jacob is not a businessman . . . he is a hired assassin . . . and his job is to neutralize problems deemed unacceptable by the corporation. But Jacob is not like other employees, nor is he like other people. After a catastrophic motorcycle accident leaves him with Cotard’s syndrome—an actual condition that causes those afflicted to believe they are dead—Jacob perceives himself as nothing but a “Shell,” with no emotions and no tether to the concept of right and wrong. Emily Buchanan is a bright young second-year associate for DBG, and she has disappeared without a trace. Suspecting that Emily has stolen either vast sums of money or valuable information from the company, Ms. Holquist, Jacob’s handler at DBG, assigns him the task of tracking down the young woman and neutralizing her. Jacob’s condition allows him to carry out assignments with ruthless, logical precision, devoid of guilt, fear, or dishonor. But as his new assignment draws him inside a labyrinthine network of dark dealings, Jacob finds himself up against something he is completely incapable of understanding. Shifting with riveting precision from New York to London, Paris to New Delhi, Spark is a thriller that delves into the surveillance state we prognosticate today . . . and will live in tomorrow. In the hands of master storyteller John Twelve Hawks, a unique character’s startling transformation comes to life, making Spark a thriller that resonates and satisfies on many levels.

Working with big data can be complex and challenging, in part because of the multiple analysis frameworks and tools required. Apache Spark is a big data processing framework perfect for analyzing near-real-time streams and discovering historical patterns in batched data sets. But Spark goes much further than other frameworks. By including machine learning and graph processing capabilities, it makes many specialized data processing platforms obsolete. Spark's unified framework and programming model significantly lowers the initial infrastructure investment, and Spark's core abstractions are intuitive for most Scala, Java, and Python developers. Spark in Action teaches readers to use Spark for stream and batch data processing. It starts with an introduction to the Spark architecture and ecosystem followed by a taste of Spark's command line interface. Readers then discover the most fundamental concepts and abstractions of Spark, particularly Resilient Distributed Datasets (RDDs) and the basic data transformations that RDDs provide. The first part of the book covers writing Spark applications using the the core APIs. Readers also learn how to work with structured data using Spark SQL, how to process near-real time data with Spark Streaming, how to apply machine learning algorithms with Spark MLlib, how to apply graph algorithms on graph-shaped data using Spark GraphX, and an introduction to Spark clustering. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
