Winnie Smith was never supposed to be that woman. She’s the responsible sister, the behind-the-scenes event planner, the one who avoids drama at all costs. So how did she end up publicly branded as the other woman—and promptly canceled by the Mommy Mafia of Cape Cod? One disastrous relationship, a missing background detail, and suddenly Winnie’s quiet life is in shambles.
Enter Lorenzo Santini, the world-renowned surgeon, feared and revered by colleagues, with zero patience for incompetence and life’s ordinary tasks. Known to hospital staff as Dr. Satan, Lorenzo needs a personal assistant—and Winnie needs a fresh start. It’s strictly business…until it isn’t.
As Winnie manages Lorenzo’s demanding schedule and carefully guarded life, she discovers there’s more beneath his intimidating exterior than arrogance and ambition. And Lorenzo begins to see that Winnie is anything but invisible.
Once in a blue moon, two people who seem to have nothing in common could turn out to be perfect for each other after all.
Winnie Smith is one of the Smith siblings, usually the quiet, responsible one. She works as an event planner until, at a child's birthday party she has organized, the boy's mother announces to everyone that Winnie is sleeping with her husband. Of course, Winnie didn't know he was married. He had given her a fake name. Soon her phone stops ringing, no one wants to hire her, and she becomes a pariah in her small town.
Then Winnie finds a new job as personal assistant to Dr. Lorenzo Santini, whom readers met in an earlier Kristan Higgins novel. Lorenzo is a brilliant surgeon who expects perfection from everyone around him. At work, he's known as arrogant and insufferable but also extremely smart and competent, and most people call him Dr. Satan. He also knows he needs help managing his life, so when his sister-in-law Lark, who is Winnie's sister, suggests Winnie, he gives her the job.
Winnie does a wonderful job organizing Lorenzo's life, and they soon discover they enjoy each other's company quite a lot. But can it work long term?
Kristan Higgins is one of my favorite romance authors, and I'll buy anything she writes. I enjoyed Once in a Blue Moon, though not as much as some of her other books. I just wish there had been a few more chapters or an epilogue.
Cliffhanger: No
