Nerdy Paisley has been attracted to gorgeous billionaire Hercules Lord since high school, but she's accepted that they'll never be more than friends — until a chance encounter changes everything.

He calls me PG, and my heart skips a beat.

Nobody calls me that but Hercules Lord, a man I've had a crush on since high school.

We could never be together, though. A romance between us is strictly forbidden. The Lords are old money, and my family, the Groves, are new money—and the Groves and the Lords don't mix. The hate between our families runs deep. Deep enough to create an invisible line in the sand that neither of us ever dared to cross.

But that's never stopped us from staring at each other from across a crowded room. And we've always been friends.

Oh... There was that one night seven years ago. I bet Hercules doesn't know that he's my first.

Yet here we are again, gazing into each other's eyes.

But tonight feels different.

We've grown up.

Our desire for each other wants to defy our restraint.

But truly, really... What will happen if we cross the line?

For fans of steamy second-chance romance, forbidden love, and the kind of heart-racing chemistry that lingers long after the last page. Crossing the Line is the first book in The Lord Brothers of Manhattan—a swoon-worthy, slow-burn series of standalone romances where passion is undeniable, emotions run deep, and love has a way of sneaking in... even when family rivalries try to stand in its way.
