Companions aren't supposed to marry dukes.
When Matilda, chaperone and aunt to the most scandalous family in London, takes a tumble from a tree, she's rescued by the most unlikely saviour. Toplofty stickler Harold, the Duke of Trensom, is more than annoyed to find Matilda on his property.

Worse when he finds himself falling for her.

Matilda is shocked at how much she wants Harry, and after all, what was wrong with a holiday fling? But when the rumour surfaces that Harry is about to propose to Delphi, her erstwhile charge, she wonders if he is playing her for a fool.
And Matilda is far from being a fool. But this time, she dares to dream.
