London's season of 1817 opens buzzing with the escapades of a jewel thief who leaves a white rose at the scene of the crime. Lord Nicholas Lucien Stratford Grey has returned to London hoping to prove that the gossip naming his cousin, Viscount Edward Turner, as the White Rose is true. As he watches his cousin across the ballroom, hating Turner for seducing his beloved and somehow causing her death, Nick sees a beautiful woman who also obviously hates his cousin.
The mysterious woman at the ball, Maggie, lives in the slums of London with two orphaned boys. Maggie is the brazen thief known as the White Rose. Her goal, as far as the boys know, is to obtain enough money for them to escape England. But Maggie has a secret motive and her instant attraction to Lord Grey can't be allowed to get in the way.
