Chi Roca has a dead girl’s voice in her head. Nearly ten years ago, her older sister Aria drowned, leaving their family shattered — and Chi has been keeping the secret of Aria’s continued presence in her mind ever since.

But Aria had secrets of her own, and as Chi has gotten older she has begun to ask questions. When Aria’s presence disappears on Chi’s sixteenth birthday, Chi decides to try to find the answers, placing herself in the same danger that led to her sister’s death.

Half a Person is a story of grief and the connections it both breaks and forges.
