Gabriel Sinclair has returned from battle as reluctant heir to a dukedom. As if his new responsibilities weren't enough, Gabriel's aunt enlists him to sponsor a young heiress through London's Little Season. Yet Miss Thea Neville is hardly the tedious obligation he expected. She's exotic and enchanting--and utterly unaware of the secret poised to destroy her family's reputation. After ten years in America, Thea is ready to do her duty and marry well. Deportment lessons, modistes, balls--the ton is a minefield she could scarcely navigate without Gabriel's help. By rights, she should accept the first bachelor who offers for her. Instead, she's succumbing to a dangerous attraction to her wickedly handsome chaperone--one that could unhinge her plans in the most delicious way.
