The year is 1937 and Andorra Kelsey - 7'11 and just under 320 pounds - is on her way to Hollywood to become a star. Hoping to escape both poverty and the ghost of her dead husband, she accepts an offer from the wily Rutherford Simone to star in a movie about the life of Anna Swan, the Nova Scotia giantess who toured the world in the 19th century. In parallel narrative, Anna Swan's story unfurls. Where Andorra is seen as a disgrace by an embarrassed family, Anna Swan is quickly celebrated for her unique size. Drawn to New York, Anna becomes a famed attraction at P.T. Barnum's American Museum even as she falls in love with Gavin Clarke, a veteran of the Civil War. Quickly disenchanted with a life of fame, Anna struggles to prove to Gavin - and the world - that she is more than the sum of her measurements. Both meticulously researched and resounding with the force of myth, The Thunder of Giants blends fact and fiction in a sweeping narrative that spans nearly a hundred years.
