Ayesha Keller was horrified by the treatment of refugees in Europe and wanted to try to make a difference. She left her job and headed for the Greek island of Lesbos, where she found the beaches strewn with discarded lifejackets, and the formal refugee settlement overflowing. Thousands of people unable to get into the camp were huddled in freezing fields, with no facilities, food or shelter. Keller banded together with other volunteers who had gone to Greece in response to the tragedy. During her year-long stay, she helped crowdfund, establish and run a transit camp in a local farmer’s olive groves.
