Newbery Medalist Cynthia Rylant captures the lively energy and warm spirit of her beloved Henry and Mudge series with this first tale starring Henry's cousin Annie and her pet bunny Snowball. Annie's birthday is coming up, and she plans to have a dress-up party. She looks forward to wearing ribbons, bows, lace, and fancy little shoes. But when the guests arrive- including Henry and Mudge-Annie learns that different people dress up in different ways....

Annie forms a club for girls who love teacups and other dainty things, but she will always love her cousin Henry and his big drooly dog too.

Annie and her bunny watch and wait as a nest is built above the porch swing, and eventually they get to see the mother bird feeding her babies.

Annie and Henry join the summer reading club at the library, and vow to be "Book Bugs" for life.

Annie goes on a surprise road trip with her dad and her pet bunny, Snowball.
