My Cold Stepbrother is the Only Cure

A secluded vacation villa filled with an overbearing male presence becomes a crisis when the heroine's life-saving suppressants vanish in the middle of the night. As the medication wears off, a struggle she has long kept hidden rises to the surface with startling force. The room she must share belongs to her stepbrother, a man known for his strict self-control and icy ruthlessness. She dreads that he will see her as a monster once her condition is exposed, but his reaction is nothing like what she anticipated.
