Books similar to Cindy Ella, Geek Charming, & Little Miss red?

I loved all the books! But sadly, Robin Palmer doesn't have anymore books. ( Well except for the new middle school series but I want to read her romance novels d: ) Does anyone have a book similar to the books above? I'm a very picky reader LOL. I liked Princess Diaries, all of Robin Palmer books, The Clique, etc. I want a fun quick teen romance novel. I don't consider Twilight, Harry Potter, and The Hunger Game Series really a romance novel. I want to read a book that is simple yet fun! Please recommend me :D thanks <3
