Four friends. Twenty years. One unexpected journey.

Eva, Benedict, Sylvie, and Lucien graduate in 1997, into an exhilarating world on the brink of the new millennium. Hopelessly in love with playboy Lucien and keen to shrug off the socialist politics of her childhood, Eva breaks away to work for a big bank. Benedict, a budding scientist who's pined for Eva for years, embarks on a physics PhD, and siblings Sylvie and Lucien pursue more freewheeling existences -- she as an aspiring artist and he as a professional partier. But as their dizzying twenties evaporate into their thirties, the once close-knit friends, now scattered and struggling to navigate thwarted dreams, lost jobs, and broken hearts, find themselves drawn together once again in stunning and unexpected ways.

A dazzling depiction of the highs and lows of adulthood, Invincible Summer is a story about finding the courage to carry on in the wake of disappointment and a powerful testament to love and friendship as the constants in an ever-changing world.
