The Summer Book, written by Tove Jansson, is a timeless classic turning 50 this year.

The profoundly humane story of the unique friendship between the little girl Sophia and her grandmother, who spend endless summer days on an island far out in the archipelago, is loved by readers around the world. As the two learn to adjust to each other’s fears, whims and yearnings, a fierce yet understated love emerges – one that encompasses not only the summer inhabitants but the very island itself.

“Wise as she was, she realized that people can postpone their rebellious phases until they’re eighty-five years old, and she decided to keep an eye on herself.”
