Istanbul, 1481. The once great city of Constantine that now forms the heart of the Ottoman empire is a strange mix of Christian, Turk and Jew. Despite the benevolent reign of the Sultan Bayezid II, the conquest is still a recent memory, and emotions run high among the inhabitants, with danger never far beneath the surface. Skiouros and Lykaion, the sons of a Greek country farmer, are conscripted into the ranks of the famous Janissary guards and taken to Istanbul where they will play a pivotal, if unsung, role in the history of the new regime. As Skiouros escapes into the Greek quarter and vanishes among its streets to survive on his wits alone, Lykaion remains with the slave chain to fulfill his destiny and become an Islamic convert and a guard of the Imperial palace. Brothers they remain, though standing to either side of an unimaginable divide. On a fateful day in late autumn 1490, Skiouros picks the wrong pocket and begins to unravel a plot that reaches to the very highest peaks of Imperial power. He and his brother are about to be left with the most difficult decision faced by a conquered Greek: whether the rule of the Ottoman Sultan is worth saving.
