I Am Pilgrim by Terry Hayes

A young woman murdered in a run-down Manhattan hotel. A father publicly beheaded in the blistering sun of Saudi Arabia. A man’s eyes stolen from his living body as he leaves a secret Syrian research laboratory. Smouldering human remains on a mountainside in the Hindu Kush.

A plot to commit an appalling crime against humanity. One thread that binds them all. One man to take the journey.
