Please answer the following question: Information:  - The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a "network of networks" that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing.  - Tom Clancy 's Net Force Explorers or Net Force Explorers is a series of young adult novels created by Tom Clancy and Steve Pieczenik as a spin - off of the military fiction series Tom Clancy 's Net Force .  - Tom Clancy's Net Force is a novel series, created by Tom Clancy and Steve Pieczenik and originally written by Steve Perry. The original series ceased publication in 2006. Relaunched in 2013, and currently written by veteran Tom Clancy author Jerome Preisler, it is set in 2018 and charts the actions of Net Force: a special executive branch of the United States government set up to combat increasing crime and terrorist activity on the Internet. There was also a spin-off of young adult books called "Net Force Explorers".  - Espionage (colloquially, spying) is the obtaining of information considered secret or confidential without the permission of the holder of the information. Espionage can be committed by an individual or a spy ring (a cooperating group of spies), in the service of a government or a company, or operating independently. The practice is inherently clandestine, as it is by definition unwelcome and in many cases illegal and punishable by law. Espionage is a subset of "intelligence" gathering, which includes espionage as well as information gathering from public sources.  - The Baltimore Orioles are an American professional baseball team based in Baltimore, Maryland. The Orioles compete in Major League Baseball (MLB) as a member of the American League (AL) East division. One of the AL's eight charter franchises when the league was established in 1901 with President Ban Johnson, this particular franchise spent its first year as a major league club in Milwaukee, Wisconsin as the Milwaukee Brewers before moving to St. Louis, Missouri to become the St. Louis Browns. After 52 often-beleaguered years in St. Louis, the franchise was purchased in November 1953 by Baltimore business interests led by Clarence Miles. The franchise officially moved to Baltimore for the 1954 season and adopted the historic "Orioles" name in honor of the official state bird of Maryland. The Orioles name had also been used by several previous major and minor league baseball clubs in Baltimore, including the franchise that would eventually become the New York Yankees. Nicknames for the team include the "O's" and the "Birds".  - Thomas Leo "Tom" Clancy Jr. (April 12, 1947  October 1, 2013) was an American novelist and video game designer best known for his technically detailed espionage and military-science story lines set during and after the Cold War. Seventeen of his novels were bestsellers, and more than 100 million copies of his books are in print. His name was also used on movie scripts written by ghost writers, nonfiction books on military subjects, and video games. He was a part-owner of the Baltimore Orioles and vice-chairman of their community activities and public affairs committees.  - A bestseller is a book that is included on a list of top-selling or frequently-borrowed titles, normally based on publishing industry and book trade figures and library circulation statistics; such lists may be published by newspapers, magazines, or book store chains. Some lists are broken down into classifications and specialties (number one best selling new novel, nonfiction book, cookbook, etc.). An author may also be referred to as a bestseller if their work often appears in this category. Well-known bestseller lists in the U.S. are published by "Publishers Weekly", "USA Today", "New York Times" and the "Washington Post". Most of these lists track book sales from national and independent bookstores, as well as sales from major internet retailers such as Amazon.com and Barnes & Noble.   - The Cold War was a state of political and military tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period (the second half of the 20th century) between 1947, the year the Truman Doctrine (a U.S. policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed.    Given the paragraphs above, decide what entity has the relation 'instance of' with 'book'.
