The Marquess’s Secret Correspondence by Henrietta Harding

Miss Aurelia Finch returned to London only to guide her young cousin through her first London season, and then disappear back into the quiet exile that had swallowed the Finch name. Yet, when a ballroom encounter brings her close to a brooding ex-military Marquess, she finds an unexpected ally, and perhaps something far more dangerous than she ever imagined: love.
Owen Honeyfield, the Marquess of Westbridge, returned from war with no patience for ballrooms or marriage markets. However, beneath his hard-won composure lies a military disaster he had never questioned until a lady -haunted by scandal- appears, and he finds himself forced to confront both the truth and the feelings he never expected…
Aurelia needs the Marquess’s secrets. Owen needs Miss Finch’s evidence. Neither expects society to embrace their fake courtship so completely, but with every letter exchanged, and every truth uncovered, pretending grows harder than either bargained for. Can a secret arrangement survive the most dangerous discovery of all?
