Jane, 12, and her grandfather encourage each other to overcome their losses and find new relationships. After his wife's death, Gramps has moved in with Jane's family, stopped wearing his teeth, and opted out of active life: he just watches TV. Then Jane's best friend, who was popular, sure of herself, and full of good ideas, moves away; Jane faces starting junior high without her. As she expects, the first day is awful, and she fears that permanent invisibility may be setting in. Then, at Mom's instigation, Jane and Gramps start attending senior citizens' dances at the Seattle Center--each having been urged to help the other through a bad time. They do; and an attractive widow and her grandson match their needs nicely, as does Gramps' advice that having friends depends on being one. Adequate light fare.
