Clary Fray learns that she is a Shadowhunter, a human-angel hybrid that hunts demons. After her mother is kidnapped, Clary must venture into the dark world of demon hunting in order to find clues that can help her find her mother.
I thought it was a really good ending. I read all the book, and in the TV show it looks like they are speeding things up a little bit. The ending was a little bit different, but I don't really care, I liked what they did. I like things that make me interesting, and changing the story a little bit will make people that read the books not able to know everything that is going to happen. They included the important parts.
The incest plot, Valentine chasing the cup, Jace and his 'darknes'. Let's now hope that they do a second season even better. And if you are not happy with the TV show, try to think about Percy Jackson's adaptations and try to be!
