Linda returns to Colombia after twenty years away. Sent to England after her mother's death when she was eight, she's searching for the person who can tell her what's happened in the time that has passed. Matty - Linda's childhood confidant, her best friend - now runs a refuge called The Anthill for the street kids of Medellín. But her long-anticipated reunion with him is struck by tension. Memory is fallible, and Linda discovers that everyone has a version of the past that is very, very different.
