This book was pretty good and I really enjoyed it! I found it very compelling and intriguing, and I loved the setting, plot, and characters. And of course, I want to read the sequel, "Emergent".
[Spoiler alert] It would be so cool if Emergent was from Elysia's child's point of view. He would have so many questions about everything! I imagine Elysia telling him: "I murdered your father..." That would be so crazy!! Of course, I'm only making this up because I have no idea what the sequel is about.
This book does contain sexual content and use of drugs, so I'd recommend it to ages 15+.
