TRIUMPH IN DUST (Twilight of Empire #6) by Ian Ross
A wonderful book, and a fitting ending to a fantastic series.
I will miss Aurelius Castus, a simple man, thrust into a far from simple world. Over seven books his character has developed and grown, he has faced down Rome's enemies time and time again, proven himself with every promotion, and now in Triumph in Dust the fate of east rests like a mountain on his shoulders.
This is a story that has a bit of everything, heart racing battles and a bitterly contested siege, coupled with political intrigue and Castus himself forced to deal with the limitations brought on by age. It may just be the best of the series.
