London's Little Season is so scandalous... It was an offhand vow often made on the battlefield. But Darby Travers, Viscount Nailbourne, now has his late comrade's young daughter on his doorstep. Worse, his new ward comes with an overprotective, mistrustful chaperone - the child's aunt, Sadie Grace Boxer. Darby is quite sure that behind her lovely facade, lies a secret. Sadie Grace faced many trials working alongside her brother in his surgery, but none prepared her for the world she's thrust into on his passing. Navigating the ton, with its endless ball gowns and parties, is difficult enough, but hiding the truth about her niece while the handsome and sophisticated Viscount watches her every move proves nearly impossible. When the past catches up with her, will she be able to trust in Darby...
