The legion of flame. #2
(Book)

For centuries, the vast Ironship Trading Syndicate relied on drake blood--and the extraordinary powers it confers to those known as the Blood-blessed--to fuel and protect its empire. But now, a fearsome power has arisen--a drake so mighty that the world will tremble before it. Rogue Blood-blessed Claydon Torcreek, Syndicate agent Lizanne Lethridge, and ironship captain Corrick Hilemore embark upon perilous quests to chase down clues that offer faint hopes of salvation. As the world burns around them, and the fires of revolution are ignited, these few are the last hope for the empire and for all of civilization.
