Lady Sophronia Bremerton is a far cry from the typical debutante, but she’s the toast of London’s upper class for one simple reason: she’s a society columnist for the London Illustrated News, and the gentry loves seeing their exploits printed in the gossip pages. But Sophie has bigger plans—she aspires to be an investigative reporter. When a stuffy ballroom during yet another Season proves to be nothing more than the usual rumor mill, Sophie seeks respite in the library, alongside four other young women who, for their own reasons, are also looking for escape. As the conversation turns to their secret ambitions, the women form a sisterhood and a bold plan: they will make their dreams a reality, no matter the obstacles. Thus begins the Blue Orchid Society.

Hearing of a murder in a London rookery, Sophie seizes the opportunity to prove her skills. Detective Jonathan Graham doesn’t believe a civilian, a noblewoman at that, should be anywhere near a murder investigation, but Sophie insists on helping bring the killer to justice. Her investigative prowess doesn’t go unnoticed by the police, especially Jonathan, who can’t decide whether this intrepid reporter is a thorn in his side or the woman of his dreams. But as the case grows more complicated and dangerous, their very lives—and their hearts—may be at risk.
