Firestarter - Mark L. Lester

Andrew and Vicky McGee met while earning money as guinea pigs for an experiment at college. The experiment was shrouded in suspicion and mystery, and seemed to be related to psychic abilities. The two were married and had a daughter Charile, who has the ability to start fires by merely thinking about it. Naturally, the government takes a great interest in Charlie, and operatives from the secret department known as "The Shop" want to quarrantine and study her.
