I liked this book. The secondary characters were really well fleshed out. I liked getting to know a wider variety of people. The romance was a little slow and dragged in some points. The one technical thing I personally would have changed was how the author used first person narrative. I felt like the immediacy of first person actually detracted from the creepy other-worldliness of Under. Maybe a limited third could have heightened the mystery. In other places it helped moved Thea's character along really well so it's just a thought.
