Cowboy's Break (Poker Flat #4)
Lexi Post

Rachel hadn’t expected to see Vance again…ever. In fact, she planned on it. Saying goodbye to him had been the hardest thing she’d ever done, but she couldn’t handle her sister, the ranch, and his job as an undercover detective all at the same time. Now she’s with him every day and buried feelings just won’t go away.
The closer Vance gets to solving the mystery of the missing money, the more convinced he becomes that Rachel is the one for him. But when prize animals start disappearing, he has to choose between revealing the culprit and keeping the woman he’s always loved from harm. He just can’t catch a break.
