First off, I love the formatting and the font. It really feeds into the fantasy feel of the book and I'm inclined to purchase prettier books. I'm not a huge fan of the cover. I would rather the cover be simpler or monochrome. I like the lightning and the sword, I just don't like the design or the color scheme as much.
I like Gemma as a character as a fierce, cunning girl who does her own thing. The writing is funny and clever. The dialogue is slightly abrasive but I believe it helps contribute to the humor in the story. The story is also fast paced which helps keep the reader's attention. The world building isn't great, but it has potential. It seems creative but the world and the habits within the world are not explained or easily implied. There were also way too many characters introduced at one time, making it difficult to keep track of who is who. This is made even more difficult to understand with the fast pacing of the book.
