Alexandre Mendonça has devoted himself entirely to his career and his two children, his heart permanently scarred by the loss of his beloved wife, Sarah. He's built walls around himself, convinced no woman could ever fill the void she left behind—until a mysterious phone call changes everything. Captivated by a sultry, sharp-tongued voice on the other end of the line, he becomes consumed with a singular desire: to meet the woman behind that intoxicating sound. Jackeline Baptista, known as Jack, is drowning in frustration. Her once-cherished job has become a source of endless stress, and everything in her life seems to be spiraling out of control. The source of her turmoil? A devastatingly handsome man with a cold, forbidding demeanor who crossed her path in an elevator at her friend's company. Unable to shake the encounter from her mind, she discovers she's somehow retained his phone number—which she mentally files under "Irresistible Ice" for the infuriatingly attractive stranger who's invaded her thoughts. When curiosity gets the better of her, she makes a call that will ignite a dangerous attraction neither of them saw coming.
