The Term Limit Bride 

Wealthy art dealer Aiden Blackstone has successfully avoided two things: returning to the hometown that haunts him, and taking a wife. Now thanks to his controlling grandfather's machinations he's reluctantly ended up doing both. But Christina Reece quickly proves she's no mere platonic bride of convenience. 

The only way she can make this marriage outlive their one-year agreement is if she can make her sexy husband open his heart and forget the demons of the past…before it's too late. Because there's an enemy on the horizon, threatening to take away all they hold dear, including their newfound passion.
