Lily Fitzhugh is desperate to get to America, where her father is imprisoned as a traitor against the Crown. To gain passage, she accepts a dangerous job: to sneak aboard a ship headed to New York and spy on suspected colonial patriot Griffin Faraday.

Griffin Faraday doesn’t trust the beautiful, tempting stowaway. He has a secret shipment of guns to deliver to General George Washington. Nothing can get in the way. But when Lily is ordered away with pirates, a sure death sentence, Griffin proposes marriage, the absolute last thing he wants.

Now Lily and Griffin are spies hiding the truth while they try not to fall in love.
Thrust into a world where deception and silence are the rule and political loyalties can mean prison or death, Lily and Griffin must face their greatest challenge—learning to trust each other.
