Forbidden Promises by Katee Robert
All Sloan O'Malley ever wanted was a simple life-and now she's finally got it. She's left everything behind in Boston--her family, her money, even her name--and set herself up in a tiny seaside town in Oregon. What she doesn't plan for? Her mysterious and painfully attractive neighbor, Jude. Jude MacNamara has been many things in his life--pampered son of a prestigious family, only surviving heir to a lost legacy, hit man--but now he's out for revenge on the man responsible for the death of his father and brothers--Colm Sheridan. He's tracking Colm's sister when he encounters Sloan living with her in her beach house. He's a patient hunter and he's willing to sit back and wait for his prey...he just doesn't expect for this woman to give rise to emotions he hasn't felt in years. He doesn't want to see Sloan hurt, but in order to protect her, he will have to turn his back on the one thing he's spent his life pursuing--revenge. Even then, there's no guarantee either one of them will make it out alive.
