Lady Rebecca has spent ten years trying to forget the boy who stole her heart—and destroyed her family. Now Lord Nathaniel is back, still recklessly charming and absolutely forbidden. A man who cares for nothing but his own pleasure.

Or so it seems. Beneath Nate’s carefully crafted façade are secrets that could tip the war against Napoleon. Nate is a spy, and he desperately needs Rebecca's help. But can she trust a feckless rake in defiance of their family feud and her brother’s mysterious plans?

When a marriage contract could bind her to a traitor, Rebecca turns to the most dangerous weapon of all—a mysterious truth serum that reveals not just lies, but the most inconvenient desires of the heart. And when the serum goes awry, half-dressed barons and ballroom scandals are the least of Rebecca’s problems.

In a world where trust leads to betrayal, can two childhood sweethearts overcome a decade of deception to save Regency England—and each other?
