I think I could sum this review up in a single line; 
 A fitting end to an amazing series! 
 Well, that's that. I'd like to add that OMG what a fantastic finale! I absolutely love Lila Bard. She is by far the best character across all three books. She plays so many roles and has such a foolhardy way of living that you can't help but like her. 
 The character I felt really bad about was Holland. Especially in ACOL. The one thing that's great about him is that he is and has never been an evil person. The situations around him have twisted whatever he has tried to do. All the amazing backstory about Holland has further made me feel bad for him. He just can't get a break. All he wants to do is improve his world and oh god he's tried so hard. The Dane twins really messed him up. (view spoiler)[ The scene at the end in the trees was really heart-breaking. He just wanted to die peacefully in his world. But he had to see it one last time back in its original failing state. (hide spoiler)] 
 Kell and Rhy were fantastic too. Their bond was explained a lot better and the scene at the end of book 2 and beginning of book 3 was enough to make you want to punch the stupidity out of Kell. Kell wouldn't last long without Lila. Or Holland. 
 Alucard played a good supporting role in this book and it was (view spoiler)[sad to see what happened to Aneesa. (hide spoiler)] His goal since book 2 was clear and he kept working on that which was great to see. 
 There's too many characters to talk about so its best to say there were none that were bad. The King and Queen played their parts impeccably and the Vesk can go stuff themselves. 
 5/5
