Shielding Grace by Sarah Stone

Grace is desperate for a change after her son’s father, Liam, dies in a tragic accident. When Liam’s overbearing parents cross the line from controlling to downright insane, Grace and her son, Josh, escape their scrutinized existence and settle into a small town. But her newfound peace is shattered when increasingly sinister messages land on her doorstep. Even Shawn—her sexy landlord and former Navy SEAL—fears what’s next. He’s everything she’s ever wanted and more, and she dares to hope for a happily ever after. But as the threats get more and more frightening, even Shawn and his military brothers might not be enough to save her.
