He's her professor. She's the one variable he can't control. Dr. Callum Hawthorne doesn't do reckless. Not anymore. After walking away from a powerful English family and leaving a scandal buried an ocean away, he's rebuilt his life-quietly, carefully-behind the lectern of a small Texas college. Everything is predictable. Contained. Safe. Until Gabrielle Clark walks into his lecture hall. She's sharp. She's relentless. She's off-limits. And she makes him forget every damn rule he's sworn to follow. What starts as a spark becomes a fire neither of them can contain. The more they try to play it cool, the hotter it burns. But secrets have mass. Consequences have gravity. And when their relationship detonates, it won't just cost them their reputations. If they're found out, he'll lose his job. She'll lose her scholarship. And the fallout won't stop there. Cal's past isn't dead. It's just buried. And secrets don't stay buried forever. Passion has a boiling point. And they're about to hit it.
