The Truth Serum: A Regency Historical Romance

By Katherine Lyons

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 fa ade 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?
