Odd runes marked its forehead, carved into the yellowed bone and filled with black ink. Its thick bottom jaw supported a row of conical fangs, long and sharp like the teeth of a crocodile. The skull sat on top of an old Stop sign. Someone had painted the surface of the octagon white and written KEEP OUT across it in large jagged letters. A reddish-brown splatter stained the bottom edge, looking suspiciously like dried blood. I leaned closer. Yep, blood. Some hair, too. Human hair. Curran frowned at the sign. “Do you think he’s trying to tell us something?” “I don’t know. He’s being so subtle about it.” I looked past the sign. About a hundred yards back, a large two-story house waited. It was clearly built post-Shift, out of solid timber and brown stone laid by hand to ensure it would survive the magic waves. But instead of the usual simple square or rectangular box of most post-Shift buildings, this house had all the pre-Shift bells and whistles of a modern prairie home: rows of big windows, sweeping horizontal lines, and a spacious layout.
