She's desperate to save her ranch. He wants to help her any way he can. Will their invented "I do" open doors that have previously been closed and lead to a happily ever after for both of them?

Callie Foster is at her wit's end when it comes to running the Shining Star Ranch. She can't give it up and let it go into foreclosure. But she doesn't know how to save it, either. Even with the help of her sister's new cowboy billionaire husband, there seems to be a never-ending string of work and bills she can't keep up with.

She's turned down offers from potential buyers because the ranch has been in her family for generations. And when Liam Walker, the handsome cowboy billionaire tech genius who moved in next door, offers her a way to keep her ranch and enjoy it, too, she sends him packing.

But Liam isn't one to give up when he knows what he wants. And he's liked Callie Foster since the day he moved in last year. She's the most stubborn woman he's ever met when it comes to getting help, but he never stops offering to make her life easier. Because, he wants her life to be easy. He wants to be the one to take care of her.

In order to save her ranch, she'll have to shelve her pride. Once she manages to do that, she goes to Liam and asks for his help. He quickly proposes a way for the Foster sisters to keep the ranch forever, and that involves an "I do" Callie's not sure she's ready to give. But as Liam spends more time with her, she starts to see him as less of a friend and more of a boyfriend. Can Liam turn his invented "I do" into a lasting relationship by Christmas?
