What books can you recommend for teens?

I have two daughters (10 and 13), they both like to read. The oldest one sets the tone for the younger sister, but my oldest daughter likes the Manga type books, as well as Happy Potter, and Hunger Games type books. She likes books that include adventure, friendship, some type of quest to follow. Their friends are not very religions and one is atheist so I am worried about how they are influencing her.
My question is: what books can you recommend for my daughters that can fit this type of profile?
I would think there are some great saint books or catholic type books that they can get excited about.

Thanks for your help.
