i had these three books, the covers where different colors (pink, green) with a girl sketched on it (i think she was blonde) in another book she gets casted by a weird photographer who ends up stalking her and in another one she is discovering illegal stuff at a house party. i read all of this during like 2010-2015 so it should be released before that timeline. i can try to find out more but i searched everywhere and all i have left is some plot memories. it had some romance in it as well but was mostly about that girl and the mysteries

How old was the girl?
