More Than Neighbors (Harlequin Super Romance Book 1968)

Temptation is so close! 

To protect her son, Mark, Ciara Malloy has moved to this rural area in Washington. The new beginning is off to a rocky start, however, when Mark gets too familiar with Gabe Tennert's horses. It's obvious their next-door neighbor prefers his solitude. Even so, he shows incredible patience with Mark. And when Gabe turns that intense gaze Ciara's way…how can she resist such a good, sexy man? 

But crossing the line between friends and something more is riskier than Ciara expects. As Gabe pushes for a commitment, she fears revealing the secret truths that could turn him away forever.
