Decker's Daughter (Cowboys of Cauldron Valley #4)
Caroline Lee

But it's not until Pops starts pressuring him to marry that he starts considering how to get those kids. He's going to have to find a wife, isn't he?
Bobbi Rae Diamon is struggling: her nursing salary covers rent and groceries for her and her six-year-old daughter, CJ, but there's not a lot left over for fun. So when CJ is offered a chance to learn to ride at a local ranch, Bobbi jumps at the opportunity...only to discover the lesson is being offered by the most drop-dead gorgeous man she's ever met.
But she learned her lesson long ago; she can't go falling in love with Decker, no matter how sweet and caring this strong-but-silent cowboy might be. And she definitely can't allow CJ to fall in love with him, because the little girl's heart is even more fragile.
So it's a good thing CJ has plans of her own, huh? If her mother is too stubborn to see reason, it's up to this determined six-year-old to bring Bobbi and Decker together!
