Michael Rowland is not your typical teenager. Deaf from birth, he's always looked out for his five-year-old brother, Joshua. When his stepfather comes after Joshua, Michael takes the child and runs. He's determined to protect his brother at all costs, even if that means making himself vulnerable to a danger he can't hear coming. And the danger intensifies when Michael witnesses a stranger kill his stepfather.
Desperate and afraid, the boys have nowhere else to go but to Joshua's soccer coach, journalist and ex-Army ranger Diesel Kennedy. When Diesel sees that Michael is injured, he takes them to see Dr. Dani Novak--not only because she's fluent in American Sign Language, but because he's drawn to her and everything she stands for. She never refuses Diesel's requests--because she, too, feels their connection--but she resists him for reasons she doesn't want to confess.
When Dani and Diesel learn that Michael saw the face of his stepfather's killer, they fear for his safety. But they quickly discover that it's even worse than they feared: They may have a serial killer on their hands--and all signs point to Michael as the next target.
