Stuck in Neutral:Terry Trueman

This is a story about a 14yr old, Shawn, who was born a quadriplegic with cerebral palsy. His father leaves the family because he has trouble accepting Shawn's condition. Shawn is able to watch sections of a TV program his father does about him, with interviews from a prisoner who killed his son who had a similar condition. Shawn knows his dad is debating with the idea of killing Shawn "to end his suffering". The book ends with Shawn's dad coming over when the rest of the family is away and Shawn has a seizure. We are left to decide if Shawn's dad takes the seizure as a sign to suffocate him.
