Honolulu, Hawaii 1941 On the evening of her sixteenth birthday party, Catherine McGarrie wants nothing more than for the night to be over, even though the opulence of the ballroom befits the daughter of a US Navy Rear Admiral. Then she meets Charlie, a navy officer from the other side of the tracks, a man her parents would never approve of. As rumours of war threaten their tropical paradise, Catherine and Charlie fall in love. But the bombing of Pearl Harbor on 7th December 1941 changes their lives forever. Seventy-five years later, addled by age and painkillers, Catherine tells her granddaughter Kit her story and reveals the tale of a long-lost treasure. Can Kit uncover the secret and reunite her family? Or will the truth tear them apart?
