ANNABELLE’S FATHER WANTS her to master her computer keyboard. Annabelle thinks the chore will be more tolerable if she writes letters to someone. She chooses Gran, her great-grandmother. Of course, Gran is most definitely not online, so Annabelle prints and mails her letters off. At first, Gran takes her time answering—and she’s in the habit of repeating herself—but soon the two are keeping up a steady correspondence. Letter by letter, a true, tender friendship evolves. Annabelle and Gran talk about everything: parents, movies, school, the past and the present. When Annabelle divulges a big secret—the reason she and her best friend are no longer speaking—Gran remembers a similar situation. And when Gran needs foot surgery, Annabelle begins to worry.
