Henrietta has a habit of making things up. Some things are true: Henrietta has a baby brother the size of a sock (almost), a crazy brown dog named Madge, and a constant hunger for chocolate ripple cake. She is good at exploring and making her dad's undies into a superb hat. Other things are not true: Henrietta says she can keep a secret. She cannot. But if Henrietta has a big habit of making things up, she has a bigger habit of making things fun, even little brothers and hamsters. So young readers are invited to come meet Henrietta, and make an irresistible, irrepressible new friend.
