Alexander Harris has always been cold and indifferent—a ruthless CEO who values power over love. Haunted by a dark past and unable to bear a woman’s touch, he vowed never to fall for anyone.

THE BILLIONAIRE'S FORBIDDEN WEAKNESS (Where the Ice Breaks) Damien Cole built his empire the same way he built his walls — brick by brick, from nothing, with bleeding hands and a heart he locked away so long he forgot it was still there. By thirty-two, he's untouchable. Ruthless. The kind of man who commands every room he enters and feels nothing when he leaves. His assistants don't last. His relationships don't either. He doesn't do warmth. He doesn't do weakness. Then Nathalia Bennett walks in. Fresh out of university, armed with ambition and absolutely zero patience for arrogance, she takes the job nobody wants — personal assistant to New York's most feared CEO. She isn't impressed by the money. She isn't intimidated by the power. And when he's cold as ice, she doesn't flinch. When he pushes, she pushes back. It should have been simple. Professional. Temporary. It becomes anything but. From the steel and glass of New York to the rain-soaked streets of London, the glittering excess of Monaco and the quiet devastation of a Bali night — something is breaking open between them. Something neither of them asked for. Something Damien will fight with everything he has, because the only thing more terrifying than his past is the possibility that she could make him forget it. He has survived everything life threw at him by feeling nothing. Nathalia Bennett is about to become the one thing he can't survive. Some walls don't crack. They shatter.

Charlotte Hartwell built Hartwell Industries from the ground up. Every late night, every sacrifice, and every success made the company more than a business—it became her life’s work. So when the powerful Blackthorne Global offers to buy her company for the fourth time, Charlotte is prepared to do what she’s always done. Say no. Darrien Blackthorne isn’t used to hearing that answer. As CEO of one of the world’s most influential corporations, he’s convinced Charlotte’s company deserves the resources to become something even greater. He isn’t trying to destroy her dream—he wants to help it flourish. But the more time he spends with the brilliant, fiercely independent entrepreneur, the less certain he becomes about where business ends and something far more personal begins. Caught between them is James—a man whose connection to Charlotte is deeper than either of them realizes. As long-buried secrets begin to surface, strange coincidences become impossible to ignore, and an unseen force quietly weaves their lives together. What began as a corporate acquisition soon unravels into something far older, far more dangerous, and far more magical than any of them could have imagined. With betrayal hiding behind a trusted smile, loyalties tested at every turn, and destiny refusing to be ignored, Charlotte must decide whether protecting the company she built is worth risking the future she was never meant to face alone. Some lives are changed by choice. Others were Entangled by Design.
