CHAD MICHAEL COX was only five years-old when his grandpa, a police officer known for crafting stories, handcuffed him and left him in a holding cell as punishment for ending a sentence with a preposition. He worked off his debt to society by diagramming sentences for his mother and accompanied his father during visits to local bookstores-a tradition Chad sustains with his own (three) children.Having grown up under such literary hardship, he continued to torment himself by studying Writing, Literature, and Publishing at Emerson College. If this wasn't bad enough, he married a girl and built her numerous bookshelves and together they accumulated a wonderfully large library, and probably, or maybe only sort of related, they serve the whims of five cats. Now, he tortures other people's children as a contract writer for Iowa Testing Programs at the University of Iowa.
