Secret Hearts by Elle Linder

A single dad and the much younger woman he refuses to live without.
There are only two things Rex Knolls really loves: his four-year-old daughter and his horses. Fifteen years ago, he gave up his wild rodeo life to settle down and open an equestrian center. He’s made several mistakes along the way but overall, life is pretty darn good. So what if he’s a little bit lonely. Running a business and raising his daughter leaves little time for love. That all changes when he meets Miss Hart, his daughter’s gorgeous preschool teacher on the first day of school.

For Tori Hart, all around her people are falling in love. She doesn’t have much hope for finding the romance she secretly desires in her small town. But then her luck changes when Rex, the father of one of her students catches her eye. He is handsome and mature, and utterly adorable the way he dotes on his daughter.

One problem…Tori’s father hates Rex and would never want his only daughter to fall in love with him.
When Tori and Rex start secretly dating, she knows she’s risking her close relationship with her dad. All she wants is for the two men she loves most to find common ground and respect each other. Is it too much to ask? Can she find love without destroying her family and get her father’s blessing?
