Hearing voices inside your head is normal, or so seventeen-year-old Onyx has been trying to tell herself over the past few weeks. She knows she's lying to herself, but there's nothing she can do about the haunting. That is until she breaks the wall inside her head and begins to speak to the voice she hears every day. The Voice promises to leave her alone, in return for a favor. If Onyx completes the task, it will disappear forever. If not, danger lies in Onyx's future. Will Onyx be able to go through with the Voice's wishes? Or will she suffer the consequences of ignoring The Voice Inside Her Head?
