He's incognito. She's in hiding. Neither of them is telling the whole truth.

Maddox McGuiness. He's the black sheep billionaire with a talent for bad press.

Delaney Sinclair. She's the family fugitive with a talent for trouble.

When Delaney drags her busted suitcase through downtown Chicago, the last thing she needs is a collision with a handsome stranger with secrets of his own. Why was he camped out in her sister's building? How much does he know? And why is his story full of holes?

She has absolutely no idea.

Then again, Mister Tall, Dark and Mysterious neglected to mention his full name. Or that he's Chicago's most infamous billionaire. Or that their collision wasn't quite the coincidence she thought.

He doesn't mention a lot of things, which leads Delaney to assume the worst. One disastrous confrontation later, it's over before it's begun.

Or is it?

She's still on his radar. He's now on her bad side. And that unforgettable kiss in Chicago meant absolutely nothing—or at least that's what Delaney keeps telling herself. Except she hasn't stopped thinking about the Chicago mystery man since.

And Maddox McGuiness? What started as a simple favor for a friend feels decidedly unfinished, because Delaney Sinclair is still driving him just a little crazy—even after disappearing.

He's not forgetting. She's not fooling. And the rumor mill isn't finished yet. When a scandal explodes, they both bolt for the same secluded place—and worst of all, together.

Sparks fly, lines blur, and better judgment doesn't stand a chance. On Mackinac Island, the off-season is anything but quiet.
