“Blue was gone without a goodbye. Robbie kept his eyes on the crow flying off as long as he could see it, but soon the black dot was out of sight, either too far or vanished into the air. Blue was headed somewhere Robert could not follow him—not yet, anyway. Robbie hoped wherever Blue was flying next would be a mystery for a long time. But he would write down the rules for haints so another kid who met another Blue would think twice before putting their life in a haint’s hands: Haints can look different ways. Haints usually come if you call their full names. Haints don’t like to be called haints. Haints can be fun as friends, but you have to look out for yourself or you might die like Redbone. Haints don’t say goodbye, except when they visit your dreams. And haints can kill you.”
