Daughter, Twin, Author

Ana and Jenna don't have much in common. Ana's father was a poor South American cabdriver who died before she hit puberty. Jenna's dad became the 43rd president of the United States the year she started college. But the two lives converged in 2006 when Jenna, a 25-year-old UNICEF intern, and Ana, a 17-year-old single mother with HIV, met during an AIDS workshop in Latin America. Out of that union came "Ana's Story: A Journey of Hope," a book by Bush for young teens that aims to raise awareness about poverty, AIDS and child abuse in developing countries. "In the U.S., we don't pay as much attention to these things, that people all over the world are living with these problems," says Bush. "The more you travel and talk to those affected by HIV, the more you know. But I'm still learning a lot, for sure."
