This is a story about hope overcoming evil, written with satisfying moral complexity. Ruth's devastation breaks apart time. She sees that her hopes and dreams are a visceral halo of rainbow colours spinning to white... and that evil dream thieves are severing these halos from sleeping victims, many of whom she knows. Those disturbing dreams of black snow lead Ruth to a perilous discovery: one dream thief is connected to her grandfather and the candle-maker's bou Jude from long ago.
