Evil/Weird/haunted/dangerous Kids
I went through a huge phase of this a few years ago so I've read quite a lot. I'll list the ones I've read below. A number of years ago, I read Perfect People by Peter James and I really loved it. I've been chasing that high ever since.
The below are the ones I've read. I remember really loving The Godsend but the rest were only ok.
The Godsend by Bernard Taylor
The Push by Ashley Audrain
The Midwich Cuckoos
The Case Against Satan (more of a possession book)
The Exorcist
Apt Pupil by King
Edit to add; Boys in the Valley. I absolutely loved it.
Available on Kindle is my other preference.
