Mostly Dead — Bonnie R. Paulson

Time is running out and Paul's original wish for death looms. As his skin grays and hunger becomes uncontrollable, the world burns. Heather and Paul have fallen for each other, but with life and death barricading them apart, and the potential cure disappearing into time, they have no hope. Paul's hunger is all-consuming. He has to walk into the flames, join Dominic, or eat everyone he loves. Can he save anyone, if not himself?(
