From one of America's most acclaimed writers, a startling and visionary novel about a race of demons who inhabit humans and wreak havoc on the lives of two small-town boys. In a small town in upstate New York, best friends Q. and Jasper live typical high school lives filled with parties and girls. When Q. starts acting recklessly, defacing lockers and misusing Bunsen burners, Jasper thinks his buddy is just letting off steam. But when his actions put both of their lives in danger, it's clear that Q. is possessed by something far more sinister than mere teenage high spirits. Meanwhile, halfway around the world in Khartoum, Ileana Magdalen is tracking an elusive man who has left a trail of blood and bodies behind him, bringing strife, war, and genocide wherever he goes.
