Something Just Like This by Jami Alden

Growing up Colleen Murphy was the girl who seemed to have it all. Pretty, smart, and popular, she had everything going for her. Now she’s back in her hometown of Big Timber, licking her wounds from a bitter divorce, mourning the death of her father, and trying to dig her mother out from under a mountain of debt. With her dreams of raising a family with a devoted husband in tatters, the last thing she’s looking to do is to get involved with another man.
Until she runs into JT Osborn, and discovers that the awkward, chubby teenager she remembers has transformed into the hottest thing in cowboy boots she’s ever laid eyes on.
Tall, built, and flashing a smile that makes her melt, JT stirs up a desire she thought had died along with her marriage. He’s the perfect friend with benefits to help her get over her ex, but she’ll never let him be anything more.

Like every guy in high school, rancher JT Osborn had a serious crush on Colleen Murphy. Back then, he could only admire her from afar, but now she’s ready for him to get up close and personal. He’s happy to do whatever it takes to put a smile back on her face. But before long, what started as fulfilling his high school fantasies has turned into much more. Now JT is out to prove that her dreams of a husband and kids aren’t dead. She can still have everything she ever wanted… with him.
