From New York Times and USA Today bestselling author Lorelei James comes a crossover story in her Rough Riders/Blacktop Cowboys® series…A May-December romance hotter than the 4th of July…Bull rider Justin Donohue spent his youth hell-bent on winning world championships. After hitting the big 4-0, Justin takes a job at the Grade A Ranch and Rodeo School, where he immediately locks horns (and lips) with the sexy, sassy Callie-a 22-year-old cowgirl set on seducing him. Discovering their age difference doesn’t deter Callie; neither does Justin’s warning that she deserves more than a busted-up former rodeo cowboy.From the moment Callie Morgan encounters the hot-as-fire new ranch hand, she knows his gruff manner is an attempt to mask his attraction to her. But she’s never backed down from a challenge, especially not when Justin’s actions speak louder than his denials. Callie doesn’t give a damn that he’s older than her or what others might think of their relationship. The uptight cowboy needs to relax and she’ll do whatever it takes to loosen him up, proving there are no age restrictions when it comes to lust…or to falling in love.
