Promised to Her by Lynn Kellan

Victor Antonov has no job, no home, and no hope after a fire destroys his restaurant. Too many people believe he started the fire, and who can blame them? He looks like a demented monster. There’s a huge scar on his face and he’s built like Frankenstein on steroids. To clear his name, he must find the man who threatened to ruin him; but Victor’s hunt for redemption can’t begin until he finds a place to live. He promises to work at an old farm in exchange for free room and board.
Nari Chen bought the farm to provide a safe place for her troubled brother, but the old house is a disaster. Accepting Victor’s help might be a disaster, too. He’s unpredictable, fiercely protective, and makes her heart stutter. She can’t afford another complicated relationship in her life while she attempts to stop her brother’s downward spiral and tame her sister’s wild streak. When Nari discovers that Victor might unearth her sister’s damaging secrets, everything changes. She must stop the formidable man she’s invited into her home…but when he finally kisses her, she doesn’t want to stop him at all.
Whenever Victor needs something, he gets a scar. Now he needs Nari to trust his unspoken promise: he’ll protect her from any threat. But when his quest to clear his name puts him at odds with the one woman who craves his kiss, Victor has to decide what’s more important: his good name or her loving kiss.
