From the international bestselling author of PACK UP THE MOON and OUT OF THE CLEAR BLUE SKY...

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.
