In 2007, Hager began marketing a book proposal with the assistance of Robert B. Barnett, a Washington attorney. The title of the book is Ana's Story: A Journey of Hope and it chronicles her experiences working with UNICEF sponsored charities in Latin America, including visits to drought stricken Paraguay in 2006, while working as an intern for United Nations Children's Fund. HarperCollins announced in March 2007 it would publish the book and it was released September 28, 2007, with an initial printing of 500,000 copies. Her share of the profits will go to UNICEF; the remainder will go to the woman whose life is the basis of the book, assisting in the young woman's continuing education. During the book tour, Hager appeared on The Ellen DeGeneres Show; during the interview Hager telephoned her parents. Hager wrote a second book, in conjunction with her mother, which is designed to encourage children to read. The book, entitled Read All About It!, was published on April 22, 2008, also by HarperCollins.
