Welcome to Book One in "The Hellion Club", the nickname for the Darrow School, where miscreant noblemen send their illegitimate daughters to keep them out of sight, out of mind, and to make them employable.

Lady Vesper Lyndhurst is beautiful, clever, and popular. Afforded every luxury as a duke’s daughter, she fills her days with friends, intrigues, and a self-professed knack for matchmaking. She may have sworn off love for herself, but she is rather excellent at arranging it. Faced with an insolvent estate, the Duke of Greydon has no choice but to return to England in a final attempt to revive his family’s fortunes. He’s been gone for years, happy to have escaped his mother and the petty circles of the ton. To his dismay, not much has changed, including the beautiful heiress next door.

Thea Knight loves a spot of mischief. She especially loves her current mischief: masquerading as her sister, while finalizing her scheme to expose the dastardly knaves whose lies ruined her life. Then big, bad-tempered Lord Luxborough upends her game by maneuvering her into marriage. But it's her sister’s name on the license, so the marriage won’t be valid. Thea’s idea? Keep pretending to be her sister until she can run away.

The fairy tale courtship did not turn into a happily-ever-after. Not until her husband dropped dead, that is. He had been horrible enough to Christiana during their short marriage, and she was not going to allow the traditional period of mourning to ruin her sisters' debuts as well. So she decides to put him on ice and go on as if nothing's happened.... Until the real earl appears.

At 30 years of age, Susan Jennings has long been considered a spinster. Exceptionally intelligent, she has little tolerance for London and the dreaded Season - if that’s how one is expected to find love, it’s not for her. But when an invitation arrives that cannot be ignored, Susan leaves her comfortable life in the country and enters the fashion and frivolity she most despises. She quickly discovers, however, that there is more to loathe in London - and his name is George Kendall.
