Cornelius Sawyer is a man of many talents, but forgiveness is not one of them.
Watt Johnson is a man of his word, but not once in his life has he spoken up for himself.
Once connected by the bonds of childhood, threads now severed by the demands of life, the pair are brought together for a once in a lifetime opportunity: an all expenses paid expedition to Brazil, searching for a man the world believes to be long dead, Percy Fawcett. And perhaps, even the Lost City that he was looking for.
Under the guise of doing research work for their respective universities, a reluctant Cornelius and an exhilarated Watt accept the offer and delve into the unknown, trusting no one but themselves. Looking at a map, the route and its dangers seem to be known obstacles which can be easily conquered, a fact that Watt leans on heavily.
But Cornelius is intimately aware that the river has teeth, that the land renders a siren song to those who are desperate to become lost in its mountains and basins. To survive the journey they'll have to face the enemies within, and trust the other to have their best interests in mind.
After all, the Voice of Wild Places is calling, beckoning the adrift homeward.
