“Caskie’s wit sparkles like a crown jewel.” — New York Times bestselling author Christina Dodd   Bestselling author Kathryn Caskie tempts historical readers once more with the Seven Deadly Sins—the deliciously licentious Sinclair family of unforgettable rogues and rapscallions—in The Duke’s Night of Sin. This latest family chronicle of passionate misadventures pits Lady Siusan Sinclair against the one man who holds in one hand the power to ruin her…and in the other, the key to her heart. If you adore the amorous exploits of Stephanie Laurens’s sinful Cynsters and Julia Quinn’s delightful Bridgerton clan—or have a passion for the romantic fiction of Lisa Kleypas and Victoria Alexander— The Duke’s Night of Sin is a night you will long remember!
