Sisters: The Karma Twist by Michelle Linn-Gust

Forced by her friends to be the first at a party to get a psychic reading, high school English teacher Sarah McCall learns more than she understands about the suicide death of her younger sister, Jenna. She dismisses the idea of a karmic agreement, that she and her sister formed a pact as souls before entering their respective lives. But, after the ten-year anniversary of Jenna's suicide passes, the reading takes Sarah on a path of reflecting on her sister's life, her own life, and their lives together tightly intertwined with baseball, oatmeal cookies, and the dream of opening a bakery. Sarah realizes she must confront her fears that Jenna’s death left behind after baseball coach Mark Lennon approaches Sarah about providing her oatmeal cookies as part of a fundraiser for his team. However, the two aspects she does not expect are how her life begins to change and her accepting that maybe she and Jenna did agree to something more than is visible in her life.
