Inseparable through university, Eva, Benedict, Sylvie and Lucien graduate into an exhilarating world on the brink of the new millennium. Eager to shrug off the hardships of her childhood, Eva breaks away to work at a big bank. Benedict stays behind to complete his PhD in Physics and pine for Eva, while siblings Sylvie and Lucien pursue a more bohemian existence.
But as their twenties give way to their thirties, the four friends find their paths diverging as they struggle to navigate broken hearts and thwarted dreams. With every summer that passes, they try to remain as close as they once were - but this is far from easy. One friend's triumph coincides with another's disaster, one finds love as another loses it, and one comes to their senses as another is changing their mind . . .
A novel about finding the courage to carry on despite life not always turning out as expected, and a powerful testament to love and friendship as the constants in an ever-changing world, Invincible Summer is a dazzling depiction of the highs and lows of adulthood and the greater forces that shape us.
