The end of days has been predicted for the last two thousand years. But now, without warning, it is upon us. Braverman 'Bravo' Shaw, member of a secret Franciscan splinter sect, has survived a battle as old as time itself: the battle between good and evil. Working with his once-blind sister, Emma, and his confessor, Fra Leoni, Bravo went to war with the Fallen, Lucifer's advance guard and emerged with The Book of Deathly Things -- Lucifer's first and last Testament. Now, back in New York, the book's secrets have revealed themselves to Emma. With the testament stolen by Bravo, Emma realizes the Fallen army will awaken fully. And come to claim what is theirs.
