ABANDONED. Fiction - superpower to go through rock/stone, and kills by pushing people through a rock/ stone

[Wendy]

I read the book in the late 1990s around the age of 10 in the UK and vaguely remember the protagonist had a thick chest and superpower to go through rocks or stones. He also kills people by pushing them into a rock/ stone... Any idea what the book could be? Thank you!
