London, 1813. In the gilded corridors of St. James's Palace, Lord Percy and Lady Grace face a mystery that could shake the throne itself. A murder and audacious theft of the Prince Regent's new ruby dagger thrusts them back into a web of deception and treachery. Tarnished by his past behavior, Lord Percy is focused on regaining favor with the ton. When the queen demands he deliver the murderer and the stolen gift, he cannot refuse. Lady Grace sees her chance to prove her value to the crown. She'll do anything to avoid endless weeks of ballrooms and beaus, even if that means being in close quarters with the man pledged to her best friend. As Lord Percy and Lady Grace wade deeper into London's underbelly, love and loyalty will face the ultimate trial. Especially since this culprit is willing to spill blood. In a society where everyone has an agenda, and half the ton is suspect, they will need to watch each other's backs. If they cannot unveil the criminal mastermind, this time it will cost them more than their reputations.
