Angel's Temper. Elemental Angels, #5

She's the only one who can break his curse, but first, she must break every rule she's ever known. If there's a list that needs following, Molly Resnick's your girl. It's how she became sous-chef at one of the most in-demand restaurants in town. When the head chef and owner suddenly quit, and the staff along with them, she takes the biggest gamble of her life by draining her savings to buy the place.
What she wasn't prepared for was the gorgeous man showing up at her door and offering himself up for dish duty. His attentive gaze and scorching heat check all her boxes and threaten to break her number one rule: no workplace romances. What's worse than a fallen angel with a fearsome temper? A curse that locks his rage inside him, slowly turning him mad. Without the ability to control his fury, he's useless against the demon charmers threatening the mortal realm.
When he recognizes a beautiful woman hanging a help wanted sign outside a restaurant, a strange energy calls to him, and he soon learns that she's the only one who can save him from his ancient curse. But fate has other plans for starved passion. When restaurant patrons fall sick and inexplicable things begin to occur, Molly and Brass must choose: let the curse remain and risk their souls or reverse the curse and risk their hearts.
