From nineteenth-century London’s elegant ballrooms to its darkest slums, a spirited young woman and a nobleman investigating for the Crown unmask a plot by Napoleon to bleed England of its gold. Chance led to Charlotte Raven’s transformation from chimney sweep to wealthy, educated noblewoman, but she still walks a delicate tightrope between two worlds, unable to turn her back on the ruthless crime lord who was once her childhood protector. When Lord Edward Durnham is tapped to solve the mystery of England’s rapidly disappearing gold, his search leads him to the stews of London, and Charlotte becomes his intriguing guide to the city’s dark, forbidding underworld. But as her involvement brings Charlotte to the attention of men who have no qualms about who they hurt, and as Edward forges a grudging alliance with the dangerous ghosts of Charlotte’s former life, she faces a choice: to continue living in limbo, or to close the door on the past and risk her heart and her happiness on an unpredictable future.

A Secret Treaty and a Secret Life LONDON, 1812: Giselle Barrington is living a double life, juggling the duties of chef with those of spy catcher. She must identify her father’s savage killer before the shadowy man finds her and uncovers the explosive political document her father entrusted to her safekeeping. Posing as a French cook in the home of Lord Aldridge, Giselle is surrounded by unlikely allies and vicious enemies. In the streets where she once walked freely among polite society, she now hides in plain sight, learning the hard lessons of class distinction and negotiating the delicate balance between servant and master. Lord Aldridge’s insatiable curiosity about his mysterious new chef blurs the line between civic duty and outright desire. Carefully watching Giselle’s every move, he undertakes a mission to figure out who she really is—and, in the process, plunges her straight into the heart of danger when her only hope for survival is to remain invisible.

The Duke of Wittaker has been living a lie... He’s been spying on the dissolute, discontented noblemen of the ton, pretending to share their views. Now he’s ready to step out of the shadows and start living a real life...but when the prime minister of England is assassinated, he's asked to go back to being the rake-hell duke everyone still believes he is to find out more. Miss Phoebe Hillier has been living a lie, too... All her life she's played the game, hiding her fierce intelligence and love of life behind a docile and decorous mask. All it's gotten her is jilted by her betrothed, a man she thought a fool, but a harmless one. But when she discovers her former fiancé was involved in the plot against the prime minister, and that he's been murdered, she realizes he wasn't so harmless after all. And now the killers have set their sights on her... The only man who can help her is the Duke of Wittaker—a man she knows she shouldn't trust. And she soon realizes he's hiding behind a mask as careful as her own. As the assassin steadfastly vows he acted alone, and as the clock ticks down to his trial, the pair scramble to uncover the real conspiracy. And as the pressure and the danger mounts, Phoebe and Wittaker shed their disguises, layer by layer, to discover something more precious than either imagined–something that could last forever. Unless the conspirators desperate to hide their tracks get to them first. Note: A Dangerous Madness is connected to the other novels in the Regency London series through an overlap of characters, but each novel is complete on its own, and you do not have to read them in order.
