The Katerina trilogy by Robin Bridges
I loved this series. I was drawn into it with the Russian politics and large families mainly because of my love of Anastasia and the mystery surrounding the Tsar and his family.
This book did not disappoint! Every minute of it I was hooked. I loved the necromancing and the splitting of the court to dark and light especially the would they, won't they match of Katerina and George. I wept a little at the end. Just one tear. But yeah I can't say anything that would summarise my experience of this trilogy other than just read it.
