The Courtesan's Protector. About An Earl, #4

Readers have been waiting for this ultra-romantic book from 10-Time USA Today Bestselling Author Jess Michaels. Former champion pugilist Campbell Ripley has been fascinated by Jane Kendall since the first time he saw her in the middle of a fight and she distracted him enough to cause his famous scar. But people like Jane and Ripley are jaded and know that a happily ever after isn't for them. The kind of powerful connection they feel can only cause pain and danger.
So they've become friends and that's all it can be. Until Jane receives word that her beloved younger sister, who she has been protecting from her life as a courtesan, has vanished. She turns to Ripely for help and the two embark on a journey to find her that will finally break down walls, allow for powerful passions and perhaps even heal more than mere physical scars. If only the two of them can let each other in and start to trust that the friendship they share and the desire they can no longer fight is actually a love that will change them both for the better.
This is the fourth book in the About An Earl series and can be read as a standalone.
