Beneath Calm Waters (Window's Point Duology, #1)

Every old house has its secrets...
When Grayson Barlow's grandfather dies under mysterious circumstances, he's forced to move back to his hometown of Widow's Point. After twelve years of running from his past, he's in no hurry to return to Barlow House or to confront the memories it holds, but he knows he now has to take care of the elderly grandmother he'd left behind.
His childhood home is exactly the way he remembered it, except his grandfather is gone and the house has gained a feisty new dog and a beautiful new caretaker, both of whom seem determined to protect the only family member he has left, even if that means driving him out before he has time to unpack his bags.
He wants nothing more than to leave, but he can't bring himself to break his grandmother's heart again. Staying means making peace, at least in the surface, with Becka Simmons, the enticing hellion who's determined to make his life miserable.
Becka is as grumpy as her pint-sized guard dog, but as he begins to understand her, he has two impossible revelations. The first is that he's in love with her. The second is that she may have killed his grandfather.
