Georgina Wilcox, a wallflower with hidden musical talents, is furious when her reclusive older sister—the recently widowed Viscountess—refuses sorely needed help from the Duke of Torrance, the only gentleman who has shown kindness to the bereft Wilcox sisters. Georgina decides to get back at her sister and shock the Viscountess by kissing the first willing stranger she meets in the enchanting gardens of Anya House. Unfortunately, her sister is not the sole witness. A group of reporters and the ton's leading gossips catch Georgina in a passionate embrace with a reticent composer, Lord Mark Sebastian.

The third son of an influential marquis, the tongue-tied Mark is determined to keep the scandal from ruining Georgina's reputation and his own prospects of winning the celebrated Harlbert's Prize for music. Under the guise of private voice lessons, the two embark on a daring gamble to fool the ton into believing that their feigned courtship is honorable while bolstering Georgina's singing genius to captivate potential suitors. Sexist cartoons, family rivalries, and an upcoming ball test the fake couple's resolve. Will their sudden fiery collaboration—and growing attraction—prove there's nothing false about a first kiss and scandalously irresistible temptation?
