However, the book's subject is more advanced.

An intellectual pig named Henrietta aspires to be admitted to Harvard Law School, but the admissions office turns her down. After the rejection, Henrietta wanders around Cambridge until she meets a vagabond philosopher who helps her achieve her dreams.

The launching of a children's book fits well with Reach Out and Read's mission. Established in 1989, the program asks doctors to encourage parents to read to their children, starting at the age of six months until the children begin school. The program also asks doctors to give parents one children's book at each checkup.

The idea is that children involved in the program will enter school with the beginnings of a home library.

"We find reading to children as young as six months helps to get them ready for entering school," said Helen L. Roberson, Reach Out and Read's office manager.

Clinton has been involved with Reach Out and Read before. She made the April 1997 announcement of a national partnership between the program and a book publisher, among others, and she also attended the program's 10-year anniversary celebration at Boston Medical Center in June.
