Whiskey Lullaby by Liliana Hart

Addison Holmes has her hands full. Marriage changes a woman, and pregnancy hormones are no joke. But despite her promise to retire from dangerous P.I. work, she has no choice but to take this case.

Twenty years ago, her father and his partner cracked the case of their careers. But it was all a set up. They sent the wrong men to prison, and now it’s time for the real culprits to tie up loose ends. Her father is dead, but his partner, who happens to be her mom’s new husband, is very much alive. At least for the time being.

Discovering the truth is no easy task, but saving her father’s legacy and her step-father’s life is her top priority. Because family means everything.
