The Last Hellion: Scoundrels, Book 4

The Duke of Ainswood, Vere Mallory - the last of the infamous Mallory hellions - lives a charmed life: he's rich, titled, and exceedingly handsome. And he's seemingly bent on throwing it all away in his reckless race toward self-destruction, until a devastatingly beautiful blonde amazon literally knocks him off his feet.

Lydia Grenville has devoted herself to protecting London's less fortunate. She has no patience for dissolute aristocrats and would like nothing more than to get his big, strong, handsome carcass out of her path so she can continue her work. But Ainswood could never resist a challenge - especially in female form - or trouble, which seems to follow Lydia like a stray puppy. When real trouble appears it's all or nothing for the duke and his annoyingly headstrong female!
