Mercy Gage knows that ink can be more dangerous than gunpowder.

In colonial Boston, Mercy operates a small print shop by day. Behind the typeset scripture and funeral notices lies another purpose: her press serves the Concordat, a secret network that carries coded messages, warnings, and forbidden truths through a city watched by soldiers.

When a trusted courier disappears and the network begins to fracture, Mercy discovers that Major Leeds is not simply hunting rebels. He is constructing a quieter form of control—one built upon records, classifications, intimidation, and the power to make people disappear without firing a shot.

Every attempt to protect the Concordat draws Mercy deeper into a struggle where evidence can save a life, expose a tyrant, or become a weapon in the wrong hands. As friends are taken and ordinary citizens discover the cost of being noticed, Mercy must decide how far she is willing to go—and whether resistance can defeat authority without becoming another version of it.

Mercy Gage is a tense historical political thriller about courage, surveillance, freedom of the press, and a determined woman who discovers that the most dangerous revolution may begin not with violence, but with a single printed page.
