An earl's daughter makes a reckless pact, leaving her reputation in the hands of a notorious rake.

She's a straitlaced silk-stocking . . .

Known as the “proper Diamond sister,” Lady Purity thoroughly enjoys adhering to the rules of society. Everything is right in her world when manners are minded and civility reigns. Clean gloves, no vulgarities, not a hair out of place!

He's a scandalous fox!

Renowned for his past indiscretions, Lord Matthew Foxford doesn't let propriety or tedious rules get in his way. By asking the pretty primster to teach him etiquette, he hopes to win her heart while loosening her tight corset.

Can Purity turn this thundering buck into a reputable nobleman without falling for his seductive charm? Or will the Fox tempt her from the well-behaved path into the garden of irreparable ruin?
