A Stormy Season by Melanie Dickerson

Nothing but the deepest love will induce Jane Gilchrist to marry, even when asked by the young and handsome widower with whom every other girl is in love.

Luke Watley lost his wife to a tragic accident. But when he discovers it was no accident at all, he must solve the mystery behind her murder, or he—and anyone close to him—is in danger of becoming their next victim.
Jane Gilchrist is maddeningly opinionated, annoyingly high-spirited, and . . . more appealing than any woman has a right to be. He seems to lose all rationality when she is near. But if he lets her get too close, she might be the next person to be killed because of his faithless first wife. But when her reputation is at stake, in an effort to do the right thing as a gentleman, he asks her to marry him. But when she agrees only to a pretend engagement, sparks of every kind begin to fly.
Jane is disgusted by the way women fawn all over the newly widowed Mr. Watley. She can’t decide if she should hate him for being so sought after, feel sorry for him for losing his wife, or kiss him when no one is looking. Whatever she decides, it’s sure to be a stormy season!
