Definitely popcorn fare. But satisfying popcorn fare.
What I like the most about it is that Berg doesn't make it too fairy-tale. The dragons? They're angry, hateful, horrible beasts, caught in a web they haven't been able to escape from, but still not cuddly monsters by any stretch of the imagination. Her protagonists are extremely flawed people, and she changes up their allegiances, hopes and dreams at almost every step of the way. That's what keeps it interesting to read. She may not be the most skilled fantasy writer in the world, but she knew how to create this story and create it well. I enjoyed it for precisely what it was.
