"While studying works on ecology in which lovers of the great outdoors and female adventurers set out to track wolves, observe mushrooms, marvel at octopuses or challenge bears, I have often thought that, if they had met my mother, they would have had before their eyes an equally fascinating creature, whose particularities have always placed me back in a familiar ecosystem, in contact with an intimacy as problematic as the one that binds us all, without our understanding very well how, to the rest of the Earth's systems." Thus begins a major book on filial love, exploring the rich range of interactions and feelings that connect us to our mothers, from birth to death and through old age. Maxime Rovere develops a profoundly innovative ethical reflection that teaches us the joyful path towards reconnecting with the world.
