The Brass Queen

In 1897, a fiery British aristocrat and an inept US spy search for a stolen invisibility serum that could spark a global war. Miss Constance Haltwhistle is the last in a line of blue-blooded rogue inventors. Selling exotic firearms under her alias, the ‘Brass Queen,’ has kept her baronial estate’s coffers full. But when US spy, Trusdale, saves her from assassins, she’s pulled into a search for a scientist with an invisibility serum. As royal foes create an invisible army to start a global war, Constance and Trusdale must learn to trust each other. If they don’t, the world they know will literally disappear before their eyes.
