From what I remember, there's a big scene in the book where two teenagers are fighting. The two main characters were away from people, hiding in the woods in a tent. They have a car with a broken spark plug. The girl has powers. She can go invisible (somewhat) and do some other things but she ends up breaking the car's spark plug because she was angry (I think?).
I read it about 3-4 years ago (2014-2015). It was in English and it did not seem super old.
