This Earl is on Fire by Vivienne Lorret

Left for dead on the doorstep of one of his properties, Liam Cavanaugh, the Earl of Wolford, is sure that he has wronged some jealous husband. And that he's definitely going to die. But his renters might have something to say about that.
The Pimm family is like no one he's ever met before. They're open, they're trusting, and they're managing to live without their servants. And their daughter Adeline is lovely. Too bad he doesn't want to marry for thirty years.
Adeline has issues. Her leg was broken when she was born, making it so that it is much shorter than her other leg. She knows how much a deformity like hers can make her a pariah, her parents used to bribe the children of their small town to come and pretend to be her friend. So she's sure that she's not going to like being in the ton; she's just in London to have adventures.
While this was a perfectly nice story, the side characters felt a bit flat, especially since at least a few of them (Julia and the Marquess of Thayne, Liam's cousin Gemma, and I'm guessing even the Earl that Thayne borrowed a horse from at the end of the story) seemed like sequel bait. The ending was also a bit rushed. Though she wasn't as well developed in this book, I remember Julia from the second book in this series and can't wait for her to get her HEA.
