Sixteen-year-old Calvin Hughes can see human energy and in that revealing light learns the best and worst of the people around him.

He tells no one what he sees, until a young girl vanishes beneath the marsh and the truth behind her tragedy is too disturbing to hide.

But when enchantments lure Cal toward the haunted waters and his sole confidante betrays him, Cal discovers the danger of knowing too much and the price for sharing secrets, especially one that could change the world.
