The Dark Days of Hamburger Halpin by Josh Berk

Things are not sounding too good for Will Halpin. In fact, Will doesn't hear sound at all because he is deaf. After an incident at his school for the hearing impaired, Will decided to give the local high school a try. Since he doesn't want to attract any more attention to himself, Will doesn't wear his hearing aids and lip reads his way through school. His size and his disability do not make him friends quickly. So far, his only friend seems to be another reject named Devon Smiley. After a tragic "accident" on the coal mine field trip, Will and Devon attempt to solve the mystery around the "accidental" death of the most popular boy in school. Will the most unlikely pair solve the mystery? Will Will ever fit in? Will Will stop eating? Read the book to find out!
