The Step Sister by Leanne Davis

Julia Lindstrom has a family who loves her, but outside circumstances make her feel like she doesn’t belong. Suffering as a teen from deep anxiety, she believes it is nature’s cosmic joke after giving her the most emotionally messy woman alive, as her mother. She lives in constant fear she will repeat the myriad mistakes that her mother has made. She then takes a new job in the construction industry and starts working for Lloyd Cartwright and Chris Vaughn. She inevitably develops a relationship with both men, and fears her life has become almost parallel to her mother’s history.

Chris Vaughn began working for his dad by accident. Now, four years later, Chris manages to make a successful and lucrative career from it. However, he half detests and half reveres the man whom he calls his boss and also his dad. Meanwhile, his boss/dad doesn’t realize their connection. Chris accidentally and quite unwillingly finds himself in the throes of competition for Julia… against his dad. But Chris must determine whether he is subconsciously trying to destroy his dad for abandoning him, or merely intending to accelerate his own ambition. Ultimately, he worries that, in the end, what he seeks and desires the most could be at odds with what he should do.
