A Red Line in the Sand is the official companion podcast to journalist David Andelman's book of the same name, published by Pegasus Books.

From the islands of the South China Sea to Korea's DMZ, the tribes of Arabia across Africa and throughout Europe, red lines have been setting agendas and changing history for centuries. A Red Line in the Sand will jump around the world in 12 episodes examining these boundaries that have changed history, set political agendas, spilled blood and smoothed paths toward peace.
