That same spring, from the wealthy city-state of Seressa, famous for its canals and lagoon, come two very different people: a young artist traveling to the dangerous east to paint the grand khalif at his request—and possibly to do more—and a fiercely intelligent, angry woman, posing as a doctor’s wife, but sent by Seressa as a spy.   The trading ship that carries them is commanded by the accomplished younger son of a merchant family, ambivalent about the life he’s been born to live. And farther east a boy trains to become a soldier in the elite infantry of the khalif—to win glory in the war everyone knows is coming.   As these lives entwine, their fates—and those of many others—will hang in the balance, when the khalif sends out his massive army to take the great fortress that is the gateway to the western world...
