★★★★
When Hagan and his brother Rogerius arrive in Constantinople in 802, on their way home to Frankland from Jerusalem, they see it only as a stop on their journey. They have fulfilled their pilgrimage and now look forward to resuming their lives among the mists and forests of their native country. But when an accidental encounter with a beautiful young woman and a gang of thugs leaves Rogerius dead, the heartbroken Hagan vows revenge. Little does he realise that this vow will draw him deep into the midst of the literally byzantine plots unfolding in the Queen of Cities, and entwine his future with that of the beautiful, charismatic, dangerous Empress Irene.
