Pony Express Hero (Saddles and Spurs, 2)

Bound by a Child 

Pony Express rider Jacob Young is a man of action, which is why when he sees a little girl caught in the middle of a stampede, he races to her rescue. And he soon discovers the child is the half sister he hadn't known he had. The more time Jacob spends with adorable Daisy and her beautiful guardian, ranch owner Lilly Johnson, the more he realizes they're filling all the lonely corners of his heart. 

Wary Lilly can't deny the cherished feelings that overcome her when Jacob vows to protect her and Daisy from any harm. And she can't help but hope that maybe they can put their past hurts aside and forge a future together as a full-fledged family.
