Katie Mullens is known as the weird kid. Dead dad. Dead mom. Loner. Maybe crazy. Always drawing in her sketch pad, and she talks to herself—or at least that’s what it looks like. But Katie is talking to real people…they’re just dead. Law Walker is drawn to Katie when he sees the sketch she’s made of a historic home—the way it looked before it burned. Law soon discovers that Katie’s sight goes beyond death, and what she sees reveals the strange, twisted history of a famous Boston family’s connection to the illegal post-emancipation slave trade.
