In a London that insists women remain quiet, dutiful, and dull, two unlikely conspirators discover a secret that awakens everything society tells them to suppress…

Jenny Rosewood – single, clever and nearly thirty, heaven forbid – has long disguised herself as a man to attend nighttime lectures and chase knowledge forbidden to her. But when an accidental alteration of her uncle’s sleeping draught unleashes a dizzying rush of freedom, Jenny sees an opportunity.

Together with Gwen Walters, a pharmacist’s wife hidden in her husband’s shadow, they form a covert sisterhood where London’s ladies gather to indulge in their secret tincture under the guise of afternoon tea.

Soon, society's most proper ladies are sipping their way toward inspiration, rebellion and risk.

Because once women taste freedom, no amount of decorum can force it back in the bottle.
