The short version: THIS BOOK IS AMAZING
The long version:
In Empire of Blood, we're introduced to the Faine siblings and follow them as they are thrown into a new world full of war and intrigue and try to figure out who they can trust and what roles they play in this world.
In Siege of Gold, multiply all of that tension and intrigue and intensity by at least ten. I did not want to put this book down, and ended up reading it in about 3 days, I think? IT'S SO GOOD. It's a solid book on its own, and as the close of a duology, it does not disappoint!
The story picks up very shortly after the end of Empire, and immediately Things Happen. Lilly needs allies, and Gabriel is starting to question whether he's chosen the right side after all. And I love how there are mirroring elements of the Faines' arcs, but how they are also distinct. There are new parts of the world to see, and new characters to meet (enemies and allies alike), and secrets that keep you guessing and also fearing for the characters (well, except Zal).
But even though the stakes are high and the world is full of darkness, Siege is not a hopeless story. There is danger. There is betrayal. There is loss and guilt and regret and uncertainty. But there is also light and loyalty and family and hope.
So if you're looking for a story set in a world full of magic and intrigue, with characters who will absolutely steal your heart (*cough cough* Annor brothers *cough cough*), the Rebel Empire is definitely a series to add to your TBR!
