First daughter Jenna Bush is writing a nonfiction book about a 17-year-old single mother in Panama who is HIV-positive that she says aims to get "kids thinking and involved," USA Today reports. The book, titled "Ana's Story: A Journey of Hope," is based on Bush's experience interning at UNICEF. It aims to "put a face on statistics" and document the lives of children in Central and South America, USA Today reports. Bush on Monday said the book is a "call to action." She added that while "not all kids can pick up and fly to Panama," there are many issues, such as HIV-related discrimination, that young people can address. The book will be published this fall by HarperCollins, the company announced on Tuesday (Minzesheimer, USA Today, 3/6). The financial terms were not disclosed, but bidding for the book reportedly topped $300,000, the AP/ABC News reports. A portion of the author and publisher proceeds will be donated to UNICEF. "We were very moved by Jenna's passion for this project," Susan Katz, president and publisher of HarperCollins Children's Books, in a statement said, adding, "Her message in this book is about hope, involvement and inclusion, told through one teenager's story of survival and strength" (AP/ABC News, 3/6). A first printing of about 500,000 copies of the book is expected (USA Today, 3/6).
