Sophomores, Chris and Fatima are an unlikely pair. He is a brilliant history student who parties like there's no tomorrow. She is a classics geek born to traditional Muslim immigrants. A budding romance perhaps, but one threatened by the smoldering disapproval of Fatima's elder brother. Though Chris and Fatima don't know it, they are caught up in a deadly game of heavenly power politics aimed at shifting the balance between the world's great religions. Enter Afriel, a defective angel with some serious personal baggage, and a mission from heaven. As Chris navigates between his studies and a madcap collection of party animals, Fatima's very survival soon hangs in the balance. Her fate—and his, are inextricably linked to the story of Afriel's strange past, a love lost eight hundred years before, and an ancient book called The Celestial Hierarchy.(SURGEON GENERAL'S WARNING: Reading this book may result in occasional outbursts of laughter, mental discomfort, and/or fits of righteous indignation.)
