Two Lives One Heart by Barbara Lynn Murphy

When techie Josie Molina is volunteered by her boss to visit an elementary school to discuss careers in Technology, she reluctantly agrees. Her reluctance vanishes when she meets and befriends teacher Trish McCann. Josie, an unapologetic lesbian, tries to ignore her attraction to Trish because getting involved with a straight woman is always a bad idea. For her part, Trish realizes that what she thought she knew about her sexuality is all wrong, and she allows herself to give in to her attraction to Josie. Once Trish is sure of her feelings, she knows she must break the news to her mother, Marilyn. In doing so, she learns of a long-buried family secret involving her grandmother Anna and her decades-long affair with her best friend Mary.

In a time when such a relationship was considered both taboo and immoral, Anna struggles to keep her family intact as she navigates her overpowering feelings for Mary. This story traverses both past and present to depict the lives of Anna and Trish as they discover their true, authentic selves.
