Amelia wakes up in the beginning of the book having forgotten everything she learned in the last one---but the chemical she manipulated to have free will decides to release her memories instead of eradicate them. With her knowledge of her teachers' treachery restored, Amelia and the other orphans break free of their school and advance out into the wide world.
Wright certainly knows how to keep up the tension. From page one I was struck by the impossibility of Amelia's situation: how can they escape when she is the only one who remembers what happened, and even she can't use any of her power? It takes a great deal of time for her to orchestrate her plan, and when she carries it out, the nature of their foes makes victory always a question.
The companionship among the five of them was wonderful, and I found myself liking even Colin a lot more than I thought I would. Sure, he's still an arrogant, leering jerk, but somewhere in the depths of that shriveled soul he does have half a heart. Victor pleased me most. I had always thought his powers in the last book were underplayed, but he shows off in spades this go-around, and it was worth the wait. His ability to manipulate matter allows him to do some awesome tricks, and his utterly logical mindset makes him unintentionally hilarious. In a battle with another logical being, they fire beams at each other and blow things up while chatting quite amicably about the probability set of me winning versus you winning....
So maybe it is geek humor, but it's the funniest, most intelligent fantasy I've read in a long time. Make no mistake, though, it will stretch your mind to read this book, if only for the sheer number of mythological personages gracing its pages. Gods and other legends seem to have half a dozen names apiece, and use them all. It can be hard sometimes to keep track of who's who. Along with that, the fact that the five main characters see the world from completely different viewpoints means they're always talking about how they interpret events. In this, Amelia wins hands down. Next up I think would be Quintin, since he went from shy and spooky to confident and really spooky (always in a good way).
After all of the battles, after every physical and magical and spiritual struggle all five of them went through to get free, the ending still manages to come around with a surprise. I won't spoil it, but I will say Amelia is not infallible, as easy as it is to make that mistake given that she's narrating the whole story. What she thought about the events at the end of the last book wasn't true, and what she started then completes itself here. The concept plays throughout the book in various subtle ways.
Now the only problem is getting my paws on the next book, which either just came out or is coming out in about a week..... Highly Recommended.
