Accident, by Dawn Garisch

Carol Trehorne's only child, Max, is in ICU with severe burns. Max, a performance artist, has set himself alight. He recovers but it becomes clear that he is planning further performances that will put him at risk of serious injury or death. Carol, a single parent and a GP in a busy suburban practice is worried that her son is not the genius his friends think he is, but might be on drugs or going psychotic.
