SADDLE UP FOR THE LOVE OF A LIFETIME 

After losing her heart—and her baby—to a disastrous romance, Lilly Lockett has her mind on only one thing: her job. She's come to the Silver Horn Ranch in Nevada to look after the Calhoun family patriarch, nothing more. But when she encounters rakish ranch foreman Rafe Calhoun, it's fireworks at first sight! 

Playboy Rafe knows his grandfather's new nurse is all wrong for him. He decided long ago that relationships just aren't in the cards. A few dates, then move on—that's been his motto. But an attempt at a casual affair with Lilly soon becomes all too serious…for both of them. And soon Rafe has to make a choice: to keep flying solo, or risk everything for a future with the woman he's come to love.
