How to Be Good is a 2001 novel by the English writer Nick Hornby.
 It centers on characters Katie Carr, a doctor, and her husband, David Grant.
 The story begins when David stops being "The Angriest Man In Holloway" and begins to be "good" with the help of his spiritual healer, DJ GoodNews (who also shows up briefly in Hornby's "A Long Way Down").
 The pair go about this by nominally convincing people to give their spare bedrooms to the homeless, but as their next scheme comes around, "reversal" (being good to people one has not been good to in the past), this proves to be fruitless and thus David gives up his strivings and his plans for a book on how to be good, appropriately named "How to be Good."

The Greater Journey: Americans in Paris is a 2011 non-fiction book by the Pulitzer Prize-winning author David McCullough.
 In a departure from McCullough's most recent works, Founding Fathers like Benjamin Franklin and Thomas Jefferson, who spent time in Paris, are not covered.

 Other subjects include Elihu Washburne, the American ambassador to France during the Franco-Prussian War, Elizabeth Blackwell, the first female doctor in the United States, and American artists who worked in Paris such as George Healy, Mary Cassatt, and Augustus Saint-Gaudens.
1776 (released in the United Kingdom as 1776: America and Britain At War) is a book written by David McCullough, first published by Simon & Schuster on May 24, 2005.
 The work is considered a companion piece to McCullough's earlier biography of John Adams, and focuses on the events surrounding the start of the American Revolution.
 While revolving mostly around the leadership (and often indecisiveness) of George Washington, there is also considerable attention given to King George III, General Howe, Henry Knox, and Nathanael Greene.
 Key Revolutionary War battles detailed in the book include the Battle of Dorchester Heights, the Battle of Long Island, and the Battle of Trenton.
 The actual signing of the Declaration of Independence is treated as a somewhat minor detail, as the main focus of the book is on military rather than political events.
 The book includes multiple pages of full color illustrations, including portraits and historical battlefield maps made by British engineers at the time.
