SOLVED. Looking for paranormal YA book titled "Nightmare". [s]

[C.]

I can't believe that I cannot find it anywhere on my bookshelves!
It was a favorite, about teens that go to an amusement park, and it seems this girl gets possessed by a spirit on a rollercoaster.

The bookcover is either pink or light blue and it is a face trying to erupt through a wall. I can't remember any more or who the author is.

This Nightmare?

Approximately when did you read it (even the decade is helpful)?

I read it about 3-5 years ago.

Y-E-S, that's it! Thank you! I have no idea why it disappeared from my bookshelves, no review or anything!

This is now solved.

That’s good, you’re welcome.
