Most Dangerous: Daniel Ellsberg and the Secret History of the Vietnam War is a 2015 non-fiction book, aimed for young adolescent readers, written by Steve Sheinkin and published through Roaring Brook Press. The multi-award-winning book tells the story of Daniel Ellsberg's role in the Vietnam War and the Pentagon Papers. Overview The book begins by telling the reader about how two members of The Plumbers are preparing to break into the office of a psychiatrist named Lewis J. Fielding, in an attempt to dig up dirt on his former client, Daniel Ellsberg, and hopefully ruin his reputation. Like a few other books by Sheinkin, it then backtracks many years, telling the reader why the government would be inclined to do such a thing. The book explains how Ellsberg got a job at the RAND Corporation, how he left to work at The Pentagon, how the Pentagon Papers were created, how Ellsberg became an anti-war advocate, and how Ellsberg accessed and released the Pentagon Papers. It often veers off Ellsberg, and tells the reader what was happening in the White House before and during the Vietnam War. The book closes off with the court cases involving the printing of the Pentagon Papers in the New York Times and Washington Post, and the case in which Ellsberg was tried for violating the Espionage Act of 1917.
