Heidi, is a novel about the events in the life of a young girl in her grandfather's care, in the Swiss Alps. It was written as a book "for children and those who love children" as quoted from its subtitle in 1880 by Swiss author Johanna Spyri.
Adelheid (final letter pronounced as a "t" sound), alias Heidi, is a girl first raised by her aunt Dete in Maienfeld, Switzerland. Dete brings 5-year-old Heidi to her grandfather, who has been at odds with the villagers for years and lives in seclusion on the alm. This has earned him the nickname Alp-Öhi ("Alp-uncle" in the Graubünden dialect). He at first resents Heidi's arrival, but the girl manages to penetrate his harsh exterior and subsequently has a delightful stay with him and her best friend, young Peter the goat-herd.
