She Loves Me by Melissa Foster

Something is off in Piper Dalton’s life, and she has a feeling it might just be her. All her siblings are blissfully settled with their forever loves. But while her sisters were dreaming of white weddings, Piper was left heartbroken and commitment phobic by her first love, her best friend’s younger brother. As a woman dominating the male-driven construction industry, Piper has no interest in turning in her hammer for an apron—even if hot and hilarious Harley thinks otherwise.
Burly bar owner Harley Dutch has a bum ankle and two preteen nieces to take care of, and having his best friend, tough-as-nails and sexy-as-sin Piper Dalton, come to his rescue is just the remedy he needs. Piper is her snarky self, and she kind of sucks at caregiving, but she’s owned his heart for years, she’s got a way with the girls, and Harley would sure like to have his way with her…
As things heat up between Piper and Harley, she warns him not to fall in love with her because she’ll only break his heart. Harley is the right man for that challenge—until he makes the biggest mistake of his life, and they begin to wonder if true love really can conquer all.
