Wild Chances by Jason Collins

ELLIS:
Carlton needs a husband—fast. He has six weeks to claim an inheritance, and he’s got his eye on me. He’s gorgeous, rich, and way out of my league. Perfect, right? No, so not right. Ever since he broke my heart way back in high school, I’ve never been able to mend it.
After all these years he’s back in town, and I can’t get him out of my sight, much less my thoughts. Falling for him could be dangerous, but that didn’t stop me before. I should be thrilled to be first in line to be his husband, but I don’t want to play a role—or watch him walk away again.

CARLTON:
My father’s left me two choices. Either come home to Wild, Wyoming, or be cut off. I never planned to go back, or to cross paths with the one good thing to come out of that town: Ellis. He’s cold—as he should be—but even now, that spark remains.
When Dad passes, I’m shocked to learn that he’s placed a condition on my inheritance. If I’m not married and settled in six weeks, I won’t see a penny. Ellis is the only man I’ve ever truly wanted, but when I tell him about the inheritance, he thinks I’ve been using him. I have to show Ellis I want to marry him, and not my father’s money.

This is the third book in the Wyoming Wilds series. It can be read as a standalone with no cliffhanger.
