Cahokia Trembles — Thomas Sabel

Troy Broadspeare's life is in shambles. His girlfriend abandoned him. His fellow professors think he's either a fraud or a fool for listening to the language of rocks. Now he's given one last chance to rescue his career. He wants to save his job. He ends up discovering the tectonic commanding rituals of the priest-kings of ancient Cahokia, the one used to control the New Madrid fault. If his nemesis doesn't kill him, he might save the country from the most destructive earthquake ever to hit the Mississippi River Valley.
