Miles Spencer has mentored tech founders for more than 30 years, and has created hundreds of jobs while founding, financing, building, and exiting three digital media companies. But he’s also strayed a long way from his US home. He led 1500 people across 14 miles of open sea in kayaks, raising more than a million dollars for charity; ran with the bulls in Pamplona, and trekked 1,100 miles through the deserts of Saudi Arabia, Jordan and Syria with his great friend, Wells Jones.

The eye-opening trek inspired Miles and Spencer to write A Line in the Sand – a best-selling sleuthing adventure capturing the essence of the Middle East through the eyes of two lifelong friends, following clues left by Lawrence of Arabia.
