Guy Gavriel Kay, bestselling author of the groundbreaking novels UNDER HEAVEN and RIVER OF STARS, once again visits a world that evokes one that existed in our own past, this time the tumultuous period of Renaissance Europe-a world on the verge of war, where ordinary lives play out in the grand scheme of kingdoms colliding.

From the small coastal town of Senjan, notorious for its pirates, a young woman sets out to find vengeance for her lost family. 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 beautiful oman, posing as a doctor's wife in her role of a spy.

The trading ship that carries them is commanded by the clever younger son of a merchant family -with ambivalence 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...
