When Anne Shirley dreamed of finding a ‘bosom friend’ in Avonlea, she did more than conjure Diana Barry into existence. The heroine of Lucy Maud Montgomery’s Anne of Green Gables (1908) imprinted on us an almost impossible standard for what to expect from our earliest female friendships: a lifelong source of joy sustained by a mutual devotion to each other’s best interests. More often than not, however – as the popularity of Elena Ferrante’s Neapolitan novels attests – childhood friendships are as complicated as any other. And when they rupture, whether through accident, argument, or design, the aftershocks can last well into adulthood.
