Her Impetuous Rakehell - The Bridgethorpe Brides, #4

Laurence Pierce never wanted a wife or children. He preferred his freedom and his bachelor's rooms in London. Then his cousin, Lord Oakhurst, dies, making Laurence guardian of a three-year-old girl. He knows nothing about children, and even less about girls. In desperation, he turns to the only lady friend he's never seduced and begs for help. Lady Hannah Lumley knows Laurence for exactly what he is, since he's been her brother's closest friend for as long as she can remember.
He's the last man she could imagine as a father, and the very last man her brother would consider letting her marry. Yet one little kiss leaves her unable to think of anything but the new Baron Oakhurst. Now her Season has taken a twist she never expected. How can the nice young lords and gentlemen in London ever compare to this impetuous rakehell?
