Most countries have been well-traveled and documented extensively. Saudi Arabia isn't one of them. Shrouded in mystery, the country and its people are relatively unknown to the rest of the world.

Alex Schlacher traveled the length and breadth of the Kingdom and was enthusiastically welcomed by people eager to shine a light on their fast-changing and increasingly modern nation.

The result is a collection of seventy portraits and stories of people living in a vast country steeped in history and on the cusp of change - from metalworkers to karate instructors, Schlacher beautifully captures the people of Saudi Arabia.
