Rancher's Son (Harlequin American Romance)

Sarah Magarity just broke the first rule of social work: don't get personally involved. But how can she ignore the orphaned tyke who shows up in her office on Christmas Eve? The chance to make a difference is awfully tempting.

So's the rancher with the sexy smile who might be the boy's father. Still, Sarah has to be nuts to let Ty Parker sweet-talk her into a cattle drive across rugged Florida wilderness.

Ty can't believe he might have a son to carry on his legacy. Still, until the DNA results come back, he isn't making any plans. But a strange thing happens on the open road. Amid rattlesnake scares and cozy campfires, he's growing closer to the boy…and to Sarah, the fiery redhead Ty can't keep out of his arms. They could be a happy family, unless the truth tears them apart….
