Former Texas Ranger and rodeo champion Ainsley Tatum will do whatever is necessary to figure out the truth surrounding her brother's death in a terrorist bombing fifteen years ago. When her boss at Vanishing Ranch hands her the opportunity to find answers, Ainsley is all in-except for one caveat.

In order to discover the truth without raising suspicions, Ainsley has to go undercover, pretending to be newly married to the man who once broke her heart.

Carter Winslow knows his father's fatal car crash was no accident. When he agrees to work with Vanishing Ranch to find answers, he never imagines what's in store for him. Pretending to be married might not be so bad . . . if his fake bride didn't despise him.

With thousands of lives potentially on the line, Ainsley and Carter must find a way to get past their differences and pull off the biggest charade of their lives. But when the deception around them deepens, the stakes grow higher and more dangerous than either could have imagined.
