By Grace Maccarone, Author & Christine Davenier, Illustrator. In four rows of two, Miss Lina’s eight ballerinas–Christina, Edwina, Sabrina, Justina, Katrina, Bettina, Marina, and Nina–dance to the park, at the zoo, and even while doing their schoolwork. They are one perfect act, but when Miss Lina introduces Regina, a new girl, the group of nine’s steps become a mess. For ages 3 and up.
