Escaping the constraints of life as a village schoolmistress, Lilia Brooke bursts into London and into Paul Harris's orderly life, shattering his belief that women are gentle creatures who need protection. Lilia wants to change women's lives by advocating for the vote, free unions, and contraception. Paul, an Anglican priest, has a big ambition of his own: to become the youngest dean of St. John's Cathedral. Lilia doesn't believe in God, but she's attracted to Paul's intellect, ethics, and dazzling smile.As Paul is increasingly driven to rise in the church, Lilia finds her calling in the militant Women's Social and Political Union. They can't deny their attraction, but they know they don't belong in each other's worlds. Lilia would rather destroy property and serve time in prison than see her spirit destroyed and imprisoned by marriage to a clergyman, while Paul wants nothing more than to settle down and keep Lilia out of harm's way. Paul and Lilia must reach their breaking points before they can decide whether their love is worth fighting for.
