Question: Are both Christopher Hitchens and Richard Llewellyn writers?
Context: The Rage Against God (subtitle in US editions: How Atheism Led Me to Faith) is the fifth book by Peter Hitchens, first published in 2010.  The book describes Hitchens's journey from atheism, far-left politics, and bohemianism, to Christianity and conservatism, detailing the influences on him that led to his conversion.  The book is partly intended as a response to "God Is Not Great", a book written by his brother Christopher Hitchens in 2007. Christopher Eric Hitchens (13 April 1949 – 15 December 2011) was an Anglo-American author, columnist, essayist, orator, religious and literary critic, social critic, and journalist.  Hitchens was the author, co-author, editor or co-editor of over 30 books, including five collections of essays, on politics, literature and religion.  A staple of public discourse, his confrontational style of debate made him both a lauded intellectual and a controversial public figure.  He contributed to "New Statesman", "The Nation", "The Weekly Standard", "The Atlantic", "London Review of Books", "The Times Literary Supplement", "Slate", "Free Inquiry" and "Vanity Fair". The Trial of Henry Kissinger is a 2001 book by Christopher Hitchens examining the alleged war crimes of Henry Kissinger, the National Security Advisor and later United States Secretary of State for Presidents Richard Nixon and Gerald Ford.  Acting in the role of the prosecution, Hitchens presents Kissinger's involvement in a series of alleged war crimes in Indochina, Bangladesh, Chile, Cyprus and East Timor. Arguably: Essays is a 2011 book by Christopher Hitchens, comprising 107 essays on a variety of political and cultural topics.  These essays were previously published in "The Atlantic", "City Journal", "Foreign Affairs", "The Guardian", "Newsweek", "New Statesman", "The New York Times Book Review", "Slate", "Times Literary Supplement", "The Wall Street Journal", "The Weekly Standard", "The Wilson Quarterly", and "Vanity Fair".  "Arguably" also includes introductions that Hitchens wrote for new editions of several classic texts, such as "Animal Farm" and "Our Man in Havana".  Critics' reviews of the collection were largely positive. Richard Dafydd Vivian Llewellyn Lloyd (8 December 1906 – 30 November 1983), known by his pen name Richard Llewellyn, was a British novelist. How Green Was My Valley is a 1939 novel by Richard Llewellyn, narrated by Huw Morgan, the main character, about his Welsh family and the mining community in which they live.  The author had claimed that he based the book on his own personal experiences but this was found to be untrue after his death; Llewellyn was English-born and spent little time in Wales, though he was of Welsh descent.  Llewellyn gathered material for the novel from conversations with local mining families in Gilfach Goch. Christopher Hitchens (13 April 1949 – 15 December 2011) was a British-American author, polemicist, debater, and journalist.  In his youth, he took part in demonstrations against the Vietnam War, joined organisations such as the International Socialists while at university, and began to identify as a socialist.  After the 11 September attacks, however, Hitchens no longer regarded himself as a socialist, and his political thinking became largely dominated by the issue of defending civilization from terrorists and against the totalitarian regimes that protect them.  He nonetheless continued to identify as a Marxist, endorsing the materialist conception of history, but believed that Karl Marx had underestimated the revolutionary nature of capitalism.  He sympathized with libertarian ideals of limited state interference but considered libertarianism not to be a viable system.  In the 2000 US presidential election, he supported the independent candidate Ralph Nader.  After 9/11, Hitchens advocated the invasion of Iraq.  In the 2004 election, he very slightly favored the incumbent Republican President George W. Bush or was neutral, and in 2008 he favored the Democratic candidate Barack Obama. Blood, Class, and Nostalgia: Anglo-American Ironies is a 1990 book by Christopher Hitchens which aims to examine the so-called "Special Relationship" between the United States and Great Britain, with a focus especially on the 20th century.  It was reissued in 2004 as Blood, Class and Empire: The Enduring Anglo-American Relationship, with a new preface by the author.  The book is not and does not purport to be a history of the relationship; it is rather, as Hitchens describes it, a series of "incisions, made at selected crucial points."  The book is dedicated to the author's wife, Carol Blue. Unhitched: The Trial of Christopher Hitchens is a 2013 book about Christopher Hitchens by the British writer Richard Seymour.  The book focuses on Hitchens's work on religion, his engagement with British politics and his alleged embrace of American imperialism.  In January 2013, Seymour said of "Unhitched", "It is written in the spirit of a trial ... I do attempt to get a sense of the complexity and gifts of the man, but it is very clearly a prosecution, and you can guess my conclusion." Mortality is a 2012, posthumously published book by Anglo-American writer Christopher Hitchens, comprising seven essays which first appeared in "Vanity Fair" concerning his struggle with oesophageal cancer, with which he was diagnosed during his 2010 book tour and to which he succumbed in December 2011.  An eighth chapter consisting of unfinished "fragmentary jottings," a foreword by Graydon Carter, Hitchens' "Vanity Fair" editor and an afterword by Carol Blue, Hitchens' widow, are also included in the publication.
