She dreams of joining the dancers on the Grand Ballroom floor as she watches, unseen, from behind plush curtains and discreet doors. She soon discovers everyone at the Buckingham - guests and staff alike - has something to hide...The storm clouds of war are gathering, and beneath the glitz and glamour of the ballroom lurks an irresistible world of scandal and secrets.
