"Newbloods, silverbloods, redbloods, it's all the same, all over again. Some who are special, some who are better than the rest, and the ones who still have nothing at all..."
You can read my review of the first book in the series, Red Queen, here.
Red Queen introduced us to a world separated by blood. Those with silver blood have incredible abilities and rule over the ordinary people with red blood. Mare was an ordinary Red who ended up having powers. Because of this, the royal family forces her to pretend to be Silver, dealing with all the intrigue and betrayals of palace life. Meanwhile, Mare joins the Red Guard, an army of Reds who are fighting against Silver rule.
Glass Sword takes place right after the events at the end of Red Queen. Highlight for spoilers: Maven betrayed Mare and is super evil and the Queen made Prince Cal kill his father, and they blamed it all on Mare.
So, Mare and Cal were on the run with the Red Guard. Among them was Mare's (presumed) dead brother, who also has abilities. They make their way to a stronghold on an island. Soon, a new leader arrives. He and Mare don't agree on the future direction of the Red Guard. She ends up leaving to hunt the Reds with powers of Silvers like her, or New Bloods as they call them.
The problem is that Maven also has the list, and Maven is also fudging nutso. He plays a cat and mouse game with Mare, almost always a step ahead of her. She finds notes from him trying to get her to give up, saying that he will stop killing New Bloods if she will return to his side. I was very sad in Red Queen because I liked Maven, and he seemed nice and sweet. I still hoped he might be redeemable, but now he's going around killing babies.
I really tried to lighten up a bit on Mare this book. In the first book, she seemed like some sort of Katniss retread. Here, she was a little annoying with her constant reminders that she is special and more important than everyone else. I decided that I wasn't being completely fair. Overall, I liked Mare and this book better once it got going. There was a heck of an ending, so I'm interested in seeing what happens next.
