Are there any other books to read related to shadow hunters and downworlders?

I read the mortal instruments and the infernal devices by candra Clare and I absolutely adored them. They are my top favourite books. Now I am waiting for the 5th book of TMI and the second book of TID, while I wait I need books that are romantic, adventurous, and of course for young adults. Any books related to the series above will be fine. I have read hush hush too, so dont suggest that,
