Previously used. Good read for ages 8-12 Fern has lived all her life with the Drudgers, extremely dull adults who worked at a firm, Beige & Beige. One day, the Beige family, the owners of the firm, visit the Drudger's house. Mrs. Drudger hopes that the Beiges' son, Milton, will one day marry Fern. Three other visitors arrive shortly after. They are the Bone family, Howard, and Mary Curtain, the nurse who delivered the Drudger's baby. Mary confesses that she had accidentally swapped their kids. Fern belonged to the Bone family, and Howard actually belonged to the Drudgers. After the Beiges leave, the Bone and the Drudgers discuss and conclude that they will try unswapping for just the summer and see how it goes.
