After a falling-out between their mothers, 13-year-old best friends Nell and Lydia are forbidden from seeing each other for the whole summer. Nell struggles with the thought of losing not only her best friend, but also the only person who offers refuge from the difficulties she faces at home. Determined to find a place of their own, Nell and Lydia spend the summer hiding out in an abandoned golf course, where they find mysterious symbols scattered throughout the grounds. As they learn the secret of the symbols, Nell discovers she isn't the only one seeking haven and begins to uncover what's really been hidden all along, finally allowing herself to be truly seen. Hidden Summer is a quietly beautiful coming of age story about self-discovery, family, and friendship. An elegantly written children’s book debut from an award-winning author in the vein of A Tree Grows in Brooklyn and for fans of Moon Over Manifest.
