xv, 242 pp. Color frontispiece and title page, and black-and-white illustrations by Pelagie Doane. Hoping to finish her education in a cultured school, Heidi's grandfather sends the adolescent to the boarding school Hawthorn, where she makes problems at the school, including by ignoring the rules by the headmistress, Miss Smith. In a few weeks, she befriends most of its foreign students and one summer break, Heidi offers one of them, Jamy, a vacation up on the Alm, saved from her parents vacating from her, and Miss Smith agrees to chaperone them. On the Alm, Smith just waits for the next train, while Jamy's necklace is lost and their track back is unsuccessful. Back up, Jamy first sights Peter's goat flock dancing before Dorfli, with Peter himself, who introduces the new little kid goat; Baerli. The next morning, Heidi meets her grandfather again, who agrees to let Jamy go up with Heidi and Peter to the goat pasture, where Peter leads the girls to the top of a nearby peak, which many of the goats follow to easily, but Distlefink gets into a dangerous situation, which Peter, Heidi and Jamy rescue him from. Back at the cabin a while later, Heidi and Jamy are sent down to get some things for Peter and his goats, but while they're gone down, she sees clouds go down over the mountains, down to the village, which come over them, while they end up staying at Reboux's mansion. A varied storm breaks and eventually, someone announces the grandfather's house is on fire. When Heidi runs out and sees it herself, she runs, repeaditly calling his name, while the others, the most of all Peter, albeit on the path, follows Heidi, catching up to her, finding his goats, then the old man himself, grieving under the fir trees. The next days, he and other villagers make plans and eventually rebuild just about the entire house, with many improvements. Grandfather telling Heidi and Jamy legends that excited the latter quite through the rest of the summer vacation and much later, at the school graduation, Heidi leaves with wishes of good luck, but also with an ridiculed mission of cheering prisoners. As an adult, is she certified to teach, but the kids arrive only after a few lonely days. One breaks the flowerpot and disappears the day after, and Heidi subsequently asks the villagers where he's gone. One night, Peter informs her he's found the child and the next day, a sudden off-railing gets them to a cave the child has reclused in, which turns out to be, the most, because of the teacher putting him and other children in the "school dungeon" Heidi had discovered. The kid's eventually back well dressed and the "dungeon" is turned back into the closets they previously were. While Peter questions Heidi of her being able to care her grandfather with her job times, Jamy accepts the invitation to replace her, but Heidi's grandfather falls sick, but which he promises to recover from, which he does, when Peter, Heidi and the villagers of Dorfli set up a wedding, after Peter asks Heidi if she would marry him, where he comes in his green Sunday suit, along with an Jamy-led children's choir of the school students and other guests including Heidi's old friend, Clara, grown into 'quite a woman' and Jamy little sister, Martha. But the couple sneaks out of their wedding to watch the sun sink again.
