He's her professor. She's the one woman he can't have.

Ryland Anderson is brilliant, powerful, and off-limits. As one of the country's most respected professors—and heir to a billion-dollar empire—he has spent years keeping the world at arm's length.

Then Millie Callahan walks into his classroom.

Sweet, ambitious, and impossible to ignore, she's the one distraction Ryland never saw coming. What begins as stolen glances and impossible attraction quickly becomes something neither of them can resist. Something that could cost them everything.

Because a professor shouldn't want his student.

And a student definitely shouldn't fall in love with the man who could lose his career, his reputation, and his future because of her.

So Ryland does the only thing he can.

He walks away.

Millie tells herself she'll forget him. Ryland tells himself he did the right thing. They never expect to see each other again.

Then Millie transfers to a university in New York, only to find Ryland standing at the front of her classroom once more.

This time, the attraction they tried to resist is impossible to deny.

Every glance feels dangerous. Every touch feels forbidden.

And every stolen moment pushes them closer to a scandal that could destroy everything. Because one mistake could cost Ryland his career. One rumor could ruin Millie's future. But the more they try to stay away from each other, the more impossible it becomes.

And temptation has a way of making smart people do reckless things.
