Mortal Instruments- text to text

This book reminds me of the series of Percy Jackson. They both are mythical.and have extra ordinary powers. They also both have to deal with fighting off evil. The main characters are both posed as the heros. In each of the stories they are filled with tons of action and excitement. They both interest me and keep me reading! They are very good and have lots of interesting characters. If you have read either of these books would you say they seem similar?
