A Bride for the Ranch Hand - Western Destinies, #4

Sophia loves Bighorn. She loves her job as a nanny. Her life is complete. Except. She's not getting any younger and she'd like to settle down. Particularly with a certain ranch hand she's got her eye on. Owen fancies Sophia. She makes his heart beat a little faster. Oh, who is he kidding. She makes it race. He's so excited that he will spend the evening escorting her to the party at the ranch. It all seems fine until catastrophe strikes.
Will a calamity force these two apart or will it bring them together?
