Viscount Breckenridge to the Rescue by Stephanie Laurens

Determined to hunt down her very own hero, one who willsweep her off her feet and into wedded bliss, and despairingof finding him in London’s staid ballrooms, Heather Cynstersteps out of her safe world and boldly attends a racy soiree.

But her promising hunt is ruined by the supremelyinterfering Viscount Breckenridge, who whisks her outof scandal—and straight into danger, when a mysteriousenemy seizes her, bundles her intoa coach, and conveys her out of London.

Now it’s up to the notoriousBreckenridge to prove himself the heroshe’s been searching for all along . . . 

Another, enjoyable light read by Stephanie laurels.  I like the description of these books by someone else "an alpha male brought to their knees by a dainty female".
