A lady with a pistol. A highwayman with a conscience. A road that demands everything. When the Bonny Rose of Berkeley Square is robbed on the Newmarket Road by the infamous Black Thorn, she loses far more than diamonds-she loses her journal, filled with scandalous truths in three languages. But the outlaw who steals it reads every word... and offers a bargain instead of blackmail. Now Lady Rosamund must choose: a gilded marriage to a man who wears her jewels like trophies, or a dangerous alliance with a fugitive who sees her as an equal. As revolution brews in France and justice rots in England, their pact ignites a chase across heaths, prisons, and storm-lashed seas-where love is the most treasonous act of all. For fans of The Scarlet Pimpernel, Bridgerton with bite, and heroines who load their own pistols.
