What are some good read alikes?

Hey im a teenager and i absoulutely LOVE Sharon Creech books. Ive read Walk Two Moons, Absolutely Normal Chaos, The Wanderer, Bloomability, etc. Ive read Harry Potter, Twilight, Percy Jackson, Red Pyramid things like that. I basically REALLY like realistic fiction teen books a lot!!! If you have any recommendations for a teenage girl that would be great! P.S. Sci Fi is fine too :)
