She was supposed to be my boss. I never expected her to become my first kiss… or my greatest temptation.

Emma Carl has spent the last decade taking care of everyone but herself. At twenty-eight, she has a demanding job as the personal assistant to billionaire CEO Luna Tim, four younger siblings depending on her, and absolutely no dating life.

Then she catches Luna kissing another woman.

Emma promises to keep her boss's secret, but keeping secrets becomes a lot harder when Luna takes her on a three-week vacation to Greece—and offers to teach Emma something she's never experienced before:

How to kiss.

What starts as innocent lessons quickly becomes something neither woman can ignore. Stolen kisses turn into secret nights, and secret nights turn into a real date beneath the stars of Santorini.

But Luna is still married.

As their attraction deepens, Emma has to decide whether she's willing to risk her career, her heart, and everything she's built for a woman who was never supposed to become the love of her life.

Because falling for your boss is dangerous.

Falling for your married billionaire boss might be impossible.

But walking away from Luna?

That might be the hardest thing Emma has ever done.
