In this exciting story, some bird kids have to stop the evil scientists that want to Thanos snap everyone that isn’t useful. What they mean by “not useful” is anyone that has a disability, a sickness or anyone that isn’t smart.The entire series is like Max telling us a story. On the back of the first book, it says something like, “I’m risking everything to tell you this.” At certain times, Max talks to the readers directly. This first-person omniscient point of view and breaking the fourth wall is a very unique writing style that I have never seen before. I can’t put into words how much this writing style fascinates me. It's also done very well because she doesn’t talk to you often but it happens frequently enough that you can notice it. It’s like when you're telling someone a story and you pause in the middle of it to talk to them directly.My favorite character in any book I've ever read would probably be Jeb. He’s so well-written because he has unclear motives. He gets you thinking and makes you feel a little like Max in how you don’t know who you can trust because he seemingly switches sides multiple times in the story. He’s also very important to the plot even if it seems like he's almost a background character.I think this series has lots of themes. A big one is that people can change. Bad people can turn into good people and vice versa. There are also some characters where at certain times you question whose side they’re on (like Jeb). Another theme is that the people in power (I mean, people behind the scenes not the official people in power) sometimes aren’t the right people. The book’s probably also saying that you shouldn’t judge people based on their disabilities or differences. It’s similar to Wolves of Beyond and Warrior Cats, because in all these books, the ones who are cast out of society are the same ones who save it.Readers who like action books would probably enjoy this series. Also people who are a bit above the recommended reading level would be able to fly through it and really enjoy the story. Based on reading level, good readers younger than the recommended age could still read the book, but they probably wouldn’t get as much enjoyment out of it. In terms of the content, I think the recommended age is appropriate.
