Alina - Comes more into her power as the Sun Summoner, but she's still conflicted about how much power is too much. She takes on an amazing leadership role, albeit slightly unwillingly.
Mal - Stop. Whining.
The Darkling - One of the yummiest villains out there. Didn't see too much of him in Siege and Storm, but he's definitely going to be around more in Ruin and Rising after this ending.
Sturmhond - He's mine and you can't have him. I really enjoyed this character - like probably one of my favorite in the series. He's clever, snarky, and a major game changer.
Toyla and Tamar - Best sidekicks ever.
Romance - Is there such a thing as a love quadrangle? Is it weird that it Leigh makes it work so flawlessly and without out the annoyance that occasionally accompanies love triangles?
Plot - Flawless. Leigh really knows how to suck readers in and turn them upside. While there are slower parts of the book, the plot doesn't necessarily drag. Even the littlest things seems to have an effect on the greater aspects of the plot. Even if you're like me, not a huge fan of high fantasy, you'll definitely enjoy Leigh's Grisha series. It doesn't feel like a high fantasy novel nor does it read like one. These books are just enjoyable, engaging, and all around entertaining.
