Geraldine Brooks weaves a rich tapestry of connection, spanning centuries, through the extraordinary life of a single racehorse. 'Horse' traverses time and perspective, embarking from Kentucky, 1850, with Jarret, an enslaved groom, and a bay foal whose uncanny understanding paves the way to exceptional victories. Amidst the chaos of civil war, an artist and the groom cross paths in a fateful reunion. Shift forward to New York City, 1954, where Martha Jackson obsesses over a mysterious equestrian painting, then to Washington, DC, 2019, where Jess and Theo, a scientist and an art historian, unravel the lost history of the Black horsemen key to the horse's success. Based on the formidable thoroughbred Lexington, 'Horse' is more than just a tale of its titular subject; it's a contemplation of art, love, and the lingering shadows of racism.
