A colleague just gave me a brief description of story/novel but doesn't remember its title but said the author's name sounded french(ish). I am trying to find it:
The story opens with a boy who can vibrate/oscillate faster than any human and in due course bends time-space. For him the rest of the people seems to stand still like trees and hence couldn't communicate with them in any manner.
At same time the rest of people (mostly his school mates), search for this boy who they believe disappeared/kidnapped.
It's mostly drama rather than focusing on the sci-fi elements.
