Which plot is better?

In 1&2, it's about students getting kidnapped and attacked by paranormal activity in the school. The next one I was thinking either a new student who's a shape shifter, he is 14 years old and his parents had to leave him with the mortals, his life was in danger, so then he looks for his parents with the tri. (Spoiler, he dies at the end) Or, a secret book that whenever a person reads it, it is a diary of a different person, beauty is in the eye of the beholder. Then the book leads to evil, because when Lily opens it a girl named Paisley Parker is the owner of the diary.
