La mappa della città morta

"The manuscript written by an explorer, and another document, are two objects that are proof for Professor Laurenzi that his son Angelo, an archaeologist who disappeared in the mountains of Mato Grosso, is still alive.... Charles Fort, director of an online newspaper dealing with mysterious news, abandons his Bolognese home and starts searching for an enigma pursued by adventurers, scholars and Criminals, for centuries: what has caused the sudden glacialization of Antarctica and the disappearance of the people of the Oltoli? What secrets are kept in the last place they would have lived and whose ruins are hidden in the Brazilian jungle? To answer these questions, Fort will have to overcome Amazon's hell and escape a powerful mining company, willing to do everything to hide knowledge that can damage global technology competition." -- cataloger's summary of the dust jacket.
