Details: This work closes a trilogy that began with "The Silent Witness", which told us about the greatness and resilience of nature and the danger to which we submit it's fragile balance, and that the sophomore " The Negationist" developed in a present day in which we refuse to see how the human being has affected and threatened that balance. In "Echoes of the Future" Aeolian embarks on a journey through the next centuries and puts us in the shoes of our counterparts from a not so distant future who will guide us on a journey through the difficulties and great dilemmas of humanity in order to survive on a planet that is increasingly inhospitable.
