Life is miserable for sixth grader Lerner Chanse at her new school. It looks like Lerner is destined to be a SLUG (Sorry Losers Under Ground) until she finds a magical worm that eats printed words instead of dirt. If Fip eats a word, that item simply disappears from the world - forever. Now that Lerner knows about Fip's magic, she has some big decisions to make. Should she eliminate crime? Or will destroying anything cause effects that she can't...
