By Hook or By Rook by Rebecca Connolly

The most dangerous journeys…
Jeremy Pratt is a spy for the Crown, and one of the best. He had been in more dangerous situations than he can admit, and has always come out unscathed. But escorting his colleague’s cousin home to her family, even in disguise, just might be beyond his skills, and the temptation beyond his ability to withstand.

May be ones of the heart…
Helen Dalton is convinced there is more to this man escorting her than meets the eye, and something familiar about him, as well. There is only one man in the world who looks at her so intensely, banters with her so easily, and makes her blush so furiously. And when he manages a daring and heroic rescue, she wonders if she ever knew him at all.
