I'm running out of book ideas help!!!

[peachyme2]

I feel like I'm running out of books to read! I read really fast and I have to narrow down my books to over 300 pages or I will finish it in a day. I read most of the time at work (I have a really easy/boring job) So I read for 8 hours strait. I need some new ideas for books to read. I only like young adult and I'm pretty in to science fiction. Here are some of my favorites.

Twilight (duh)

Mortal Instruments

Gemma Doyle Trilogy

Hunger Games

wicked lovely

I don't just read series but there are too many books to name off. So if anyone has ideas of books I would like with over 300 pages please please please let me know!! THANK YOU!!
