The author follows her fiancé to war-torn Congo to study extremely endangered bonobo apes – a species with whom we share 98.7% of our DNA. As she embraces her new surroundings, she probes life's greatest question: What ultimately makes us human? Her investigation teaches her a new truth about love and belonging. "Eyre recreates the scenes like a visual artist, nuanced shifts in her voice as planned out as every stroke of a brush. It's easy to get lost in the story."—Publishers Weekly
