Abigail's groundbreaking research holds the key to saving her brother's life, but with time and options slipping away, she faces an impossible challenge. The path to success demands a visa and a fortune beyond reach. In her darkest hour, her loyal best friend presents an irresistible solution: a marriage of convenience to her wealthy and captivating brother, Connor. He's adamant about keeping it strictly business.

For Abigail, it's a pragmatic transaction—a means to an end. Love has no place in her mission-driven world. But as fate intertwines their lives, their undeniable chemistry becomes an unexpected complication.

Haunted by his past and the loss of his fiancée, Connor agrees to the charade solely to aid his sister. Little does he know, Abigail will awaken emotions he never thought possible. Will he shatter the walls he built around his heart, or will their sham marriage remain a mere business arrangement?

In this gripping tale of love and sacrifice, time ticks away, forcing Abigail and Connor to confront their deepest desires. Will they find the courage to rewrite their destinies, or will fate conspire to keep them apart?
