Amazon. The Parthian Chronicles, #9

Congratulations on reaching a landmark birthday, Pacorus. And to celebrate the gods have sent you a present. As your friends gather at Dura to commemorate the man who is a Parthian legend, the immortals send a storm from the east to plunge the empire into fresh conflict. Do not be angry. They honour you and wish to see you doing what you do best, warlord, no matter how much blood is shed. As friends are lost and the peace he has fought so hard for crumbles before his eyes, a weary Pacorus is forced to lead his army once more into battle.
But the new campaign is different from previous ones, as old enemies become new allies and the world and certainties he has known are turned upside down. Can he restore the man he has pledged his allegiance to, or will the powerful rebel alliance prove irresistible and create a dark chasm into which Parthia will be sucked?'Amazon' is the ninth volume in the Parthian Chronicles and follows on from 'The Cursed Kingdom'.
