Query: Not my thing

This might be a better movie than it is a book. The writing itself is good and for those who enjoy reading this type of book, I'm sure it's fine but I have trouble getting serious about trolls and vampires who are recruited to fight a war. The girl, Polly, is enjoyable and the plot of her trying to find her brother dressed as a boy is interesting and I keep reading because of her and just tolerate the rest of the characters.
