If you're looking for something that will open with a bang and keep you up late because you have to know what happens, you just found it! I don't read a lot of fiction, and even less that's directed towards young adults - but this was awesome.
The pacing was perfect - it never dragged or felt rushed. The characters' responses to finding themselves in crazy situations were realistic and age appropriate without being shallow and annoying; that was a rare and much-appreciated bonus.
I usually dock stars for glaring typos and editing glitches, of which there were a few, but everything else about this book was so great that I decided not to this time. For anyone who likes science fiction, comic books, or aliens this series is a must-read! (And really, how can you not like something with chaos right in the title? Lol)
