My book in progress, The Un"veil"ing

I'm writing a book for school and have bits and pieces, I've written a summery, and several scenes!
I'd love some opinions on this, help, criticism, ideas, anything!

Small towns are stereotypically "Boring". Bellebrooke, Maine is quite the contrary. Once every ten years, a local teenager is chosen to slip out of reality, and into the veil when they sleep. The towns "outcast" Trevor Quinn was chosen for this. It started out normal, talking to spirits and seeing the dead. But then one day he did not wake back up. How will he get out?
